Öğe Anatomical variations of the circle of Willis in children(Springer, 2021) Solak, Serdar; Ustabasioglu, Fethi Emre; Alkan, Aykut; Kula, Osman; Sut, Necdet; Tuncbilek, NerminBackground The morphology of the circle of Willis in adults has been thoroughly discussed in scientific literature. However, the morphology of the circle of Willis in pediatric patients is under-researched. Objectives We aimed to establish reference data for the morphology and variations of the circle of Willis in a population consisting of all pediatric age subgroups and to evaluate the possible temporal evolution of the circle of Willis in pediatric patients along with the variations between pediatric and adult populations. Materials and methods Our patient cohort included 263 pediatric patients ages 1-215 months. A total of 273 magnetic resonance (MR) angiography images were retrospectively analyzed for all circle of Willis vessels to compare the incidence of complete cases and variation frequency based on gender and age group. Result In our study of 273 MR angiograms from all age ranges in the pediatric population, we found a 56.1% circle of Willis completion rate. Overall completion rates were statistically significantly higher in the toddler and preschool age groups. The lowest completion rate was in the newborn-infant group (40%). Conclusion Circle of Willis completion rates and variations in pediatric populations are similar to those in adult populations; completion rates rise in toddler and preschooler age groups and decline as children grow into the school-age and adolescent period.Öğe Assessment of Duodenal Diverticula: Computed Tomography Findings(Bentham Science Publ Ltd, 2019) Yilmaz, Erdem; Kostek, Osman; Hereklioglu, Savas; Goktas, Muhammet; Tuncbilek, NerminAims: To demonstrate the prevalence, accompanying pathologies, imaging and follow up findings of Duodenal Diverticula (DD) with Multidetector Computed Tomography (MDCT). Materials and Methods: Consecutive 2910 abdominal MDCTs were retrospectively reviewed on axial, coronal and sagittal planes. DD were evaluated for prevalence, location, number, size, contents, diverticular neck, accompanying pancreaticobiliary pathologies, jejunal and colonic diverticula, respectively. Results: DD were diagnosed in 157 cases (5.4%) and found mostly in the second part of the duodenum. Juxta-ampullary DD was the most common type (78.3%) and mostly located ventral (n:86, 69.9%) to the ampulla of Vater. DD was solitary in 123 patients (78.3%) and more than one in 34 patients (21.7%). The median diameter of DD was 2.5 cm (range 1.5-3.6 cm) in the long-axis. The lumen of DD contains air and contrast agent (n:96, 61.1%); air, contrast agent and debris (n:42, 26.7%) in most cases. Colonic diverticula (n:36, 22.9%), cholelithiasis (n:32, 20.4%), choledocholithiasis (n:7, 4.4%), and biliary dilatation (n:8, 5.1%) were the most common additional findings. Median follow-up time was 23 months (range 11 to 41 months). In three cases, new findings (cholelithiasis, n:3, choledocholithiasis, n:1) were detected. Conclusion: Accompanying pathologies with DD diagnosis are valuable for physicians in order to manage the patients. Following clinical and radiological features of well-diagnosed DD might reduce the possible complications.Öğe Breast Conserving Surgery and Sentinel Lymph Node Biopsy in Locally Advanced Breast Cancer: Single Center Experience(Galenos Publ House, 2011) Sezer, Atakan; Alas, Rusen Cosar; Cicin, Irfan; Hoscoskun, Zeki; Tuncbilek, NerminObjective: Patients with locally advanced breast cancer may undergo breast conserving surgery after neoadjuvant chemotherapy. The aim of the study is to evaluate the results of locally advanced breast cancer patients who underwent breast conserving surgery, axillary dissection and sentinel lymph node biopsy in a single center. Material and Methods: 12 patients with locally advanced breast cancer stage IIIA/IIIB were included in the study between 2002-2009. The patients were given anthracycline-based regimen before surgery. Patients underwent breast conserving surgery, axillary dissection, and sentinel lymph node biopsy followed by radiotherapy. Results: There were five patients in stage IIIA, six in stage IIIB, and one in stage IIIC. Patients had received 3-6 regimen of FAC/FEC. Eight had partial and four had complete response. Five positive axilla were detected. The median value of the lymph nodes was 12 (n:8-19). Five patients underwent sentinel lymph node biopsy. The biopsy has failed in one patient and the median value of dissected sentinel node was 3.5 (n:3-4). Locoregional recurrence was not observed in any patients. The mean follow-up of the patients was 29.8 months and median time was 16 (n:2-80) months. Of the 12 patients 10 are alive and 2 were deceased. Conclusion: In selected locally advanced patients, breast conserving surgery and sentinel lymph node biopsy may be applied by a multidisciplinary approach, and excellent success may be achieved in those patients as in early breast cancer patients.Öğe Cerebral sinus thrombosis in patients with inflammatory bowel disease: A case report(Baishideng Publishing Group Inc, 2005) Umit, Hasan; Asil, Talip; Celik, Yahya; Tezel, Ahmet; Dokmeci, Gulbin; Tuncbilek, Nermin; Utku, UfukInflammatory bowel disease (IBD) is an idiopathic inflammatory disease of the gastrointestinal tract. The pathophysiology of IBD is probably the result of the complex interaction of genetic susceptibility and environmental influences. There is a well-known risk of thrombosis in patients with IBD. We present the case of a 53-year-old man with ulcerative colitis, who spontaneously developed intracranial sinus thrombosis that was treated with low molecular weight heparin. Literature was searched to assess the frequency and characteristics of cerebral sinus thrombosis in IBD and the role of certain etiopathological factors in such thrombotic patients.

Eighteen of them received sunitinib and the rest/remaining received pazopanib in the first line of mRCC treatment. Baseline and follow-up computed tomography studies of the patients were performed to measure cross-sectional areas (cm(2)) of muscle tissues.ResultsAbout 69% of patients were male and median age was 60 (49-68)years. Median time interval between two CT imagings was 6.1 (3.1-7.7)months and it was similar between the two groups (for sunitinib, 4.9 (2.5-6.9)months vs for pazopanib, 7.3 (3.2-9.5)months, p=0.16, respectively). Disease control rate was 77.7% in all patients. Of these, 66.6% in sunitinib group was consisted of four partial responses and eight stable diseases. In addition, 88.8% in pazopanib group was consisted of three partial responses and 13 stable diseases. A significant decrease in SMA and LBM was observed after sunitinib therapy, whereas SMA and LBM values of pazopanib group did not change significantly (p=0.02 and p=0.70, respectively). No significant differences were observed between patients with sunitinib, and pazopanib group median PFS [11.9 (95% CI 6.1-17.6) vs 8.1months (95% CI 7.2-9.1), respectively; p=0.28] and median OS [28.6 (95% CI 24.3-32.9) vs 25.5months (95% CI 18.9-52.7), respectively; p=0.42]. Dose-limiting toxicities were significantly more frequent in sunitinib group than in pazopanib group (66.7% vs 22.2%, p=0.02, respectively).ConclusionsLoss of SMA and LBM with sunitinib was more substantial than with pazopanib. Treatment efficacies of both drugs were similar, but dose-limiting toxicity was more frequent in sunitinib group. Loss of SMA had no significant association with prognosis. Further studies are needed to clarify the possible association between SMA and prognosis in mRCC patients who receive sunitinib or pazopanib.Öğe Complete agenesis of dorsal pancreas with pancreatic cyst: A case report(Kare Publ, 2021) Ustabasioglu, Fethi Emre; Kurt, Nazmi; Tuncbilek, NerminAgenesis of the dorsal pancreas (ADP) is extremely rare disease with no specific symptoms and there is no clear pathogenesis. Approximately half of the affected individuals develop diabetes resulting from reduced islet cell mass secondary to lack of endocrine structures. In this case, we aimed to present a 17-year-old female patient with ADP accompanied by a pancreatic cyst.Öğe The effects of fat distribution and some adipokines on insulin resistance in subjects with prediabetes(Via Medica, 2016) Bilir, Betul Ekiz; Guldiken, Sibel; Tuncbilek, Nermin; Demir, Ahmet Muzaffer; Polat, Ahmet; Bilir, BulentIntroduction: The risk of developing insulin resistance and metabolic syndrome is particularly high in central obesity. In this study we evaluated the effects of fat distribution and some adipokines on insulin resistance in prediabetic patients. Material and methods: Eighty-seven age- and sex-matched patients were divided into three groups according to their 75-gram oral glucose tolerance test results as follows: impaired fasting glucose group, impaired glucose tolerance group, and normal glucose tolerance group. Fasting insulin levels were measured. Homeostatic model assessment of insulin resistance was calculated. Body fat mass measurements were assessed by bioelectric impedance analyser and abdominal fat thicknesses (subcutaneous, visceral, and preperitoneal) by ultrasonography. The fasting serum levels of several adipokines [adiponectin, leptin, resistin, vaspin, visfatin, retinol-binding protein-4 (RBP-4), tumour necrosis factor-alpha (TNF-alpha)] were measured by ELISA method. Results: The mean body mass index, fat mass measurements, and abdominal fat thicknesses of the groups were similar. There were no differences between groups in terms of the mean fasting insulin, vaspin, RBP-4, leptin, resistin, and TNF-alpha. In comparison of the prediabetic and normal groups, the levels of adiponectin (p < 0.001) and visfatin (p < 0.001) were lower in the prediabetic group. Furthermore, we found that high body mass index (p < 0.01) and fat mass (p < 0.01) and low adiponectin (p < 0.05) levels have roles in the development of insulin resistance in the prediabetic group. Conclusions: We suggested that in the prediabetic period not only obesity but also decreased adiponectin levels play some role in the pathogenesis of insulin resistance.Öğe Evaluation of morphine effect on tumour angiogenesis in mouse breast tumour model, EATC(Humana Press Inc, 2011) Ustun, Funda; Durmus-Altun, Gulay; Altaner, Semsi; Tuncbilek, Nermin; Uzal, Cem; Berkarda, SakirBreast cancer is the leading cause of death among women, and morphine is used to relieve the pain of patients with cancer. The data on the effects of morphine on tumour growth and angiogenesis are contradictory. We determined in mouse breast cancer model whether analgesic doses of morphine would affect tumour angiogenesis, and then the correlation between microvessel density (MVD), Doppler sonography (DS) and Tc-99m-Tetrofosmin (TF) uptake. Ehrlich ascites tumour cell xenografts, Pgp-negative tumour were divided into two groups: (a) Morphine sulphate [0.714 mg/kg/day (equivalent to 50 mg per day for a 70 kg human)], (b) no-morphine. For the determination of angiogenesis in mice tumour tissue, TF scintigraphy, microvessel density and DS were done. MVD was significantly different between groups (49.4 +/- 1.8 vs. 41.8 +/- 1.9, morphine and no-morphine groups, respectively, P < 0.001). A strong correlation was found between late uptakes of mass at scintigraphy and degree of angiogenesis in histopathologic examination (r = 0.52, P < 0.01). There was statistically significant inverse correlation between degree of angiogenesis in histopathologic examination and washout ratio of TF (r = 0.40, P < 0.05). The higher values for angiogenesis are related to higher TF reuptake. There was no statistically significant correlation between DS and TF. A strong correlation was found between MVD and grade of DS (r = 0.51, P < 0.01). Our preclinical mice study indicates that morphine at clinically relevant doses stimulates angiogenesis, and angiogenesis triggered of morphine is demonstrated with MVD and DS, but not TF. However, uptake and washout of TF are compared with immunohistochemically assessed morphine-stimulated angiogenesis in tumour tissue.Öğe Evaluation of placenta in patients with gestational diabetes using shear wave elastography and superb microvascular imaging(Sage Publications Ltd, 2024) Celik, Ahmet Onur; Gunay, Burak; Coker, Gonca Busra; Ustabasioglu, Fethi Emre; Ates, Sinan; Tuncbilek, NerminBackground: Gestational diabetes mellitus (GDM) is a common disease, and the placenta shows various functional and morphological changes in these patients. Superb microvascular imaging (SMI) and shear wave elastography (SWE) are innovative ultrasound (US) methods that provide detailed information about tissue vascularization and elasticity.Purpose: To evaluate placental changes in patients with GDM with SMI and SWE methods.Material and methods: For this case-control study, 20 healthy and 20 women with GDM were included. Women at >21 weeks of pregnancy were evaluated with SMI and SWE by two independent radiologists. Mean SMI values and mean SWE values from three different region of interest-based measurements were compared between the two groups.Results: We identified that the mean SMI and SWE value of the GDM group was found to be significantly higher than that of the control group (P = 0.002, P = 0.001 respectively). Using a receiver operating characteristic curve, the cutoff value of the SMI ratio, which maximizes the prediction of the presence of GDM, was 0.1234279750 (95% confidence interval [CI] = 0.625-0.920), the SWE cut-off value was 15.5 kPa (95% CI = 0.794-0.989).Conclusion: We have demonstrated that evaluation with SMI and SWE might allow quantitative assessment of the morphological changes of placentas in women with GDM. We believe that the use of innovative methods such as SMI and SWE in addition to conventional US examinations in daily practice and studies will provide significant clinical benefits to patient management.Öğe Fibroadenoma of Axillary Ectopic Breast Tissue(Ubiquity Press Ltd, 2021) Kurt, Nazmi; Demirtas, Elif Mercan; Tuncbilek, NerminTeaching point: Ectopic breast fibroadenoma is a rare benign neoplasm that may mimic pathological lymph node clinically and on imaging.Öğe Intrathoracic extrapleural lung herniation: A new type of lung hernia(Kare Publ, 2021) Ozgur, Cihan; Ustabasioglu, Fethi Emre; Tuncbilek, Nermin[Abstract Not Available]Öğe Investigation of insulin resistance gene polymorphisms in patients with differentiated thyroid cancer(Springer, 2014) Akker, Mustafa; Guldiken, Sibel; Sipahi, Tammam; Palabiyik, Orkide; Tosunoglu, Ayhan; Celik, Ozlem; Tuncbilek, NerminWe aimed to investigate insulin receptor substrate-1 (IRS-1), insulin receptor substrate-2 (IRS-2), insulin-like growth factor binding protein-3 (IGFBP-3) genotypes, which are thought to be involved in the pathogenesis of many solid tumors and have thus far not been studied in patients with differentiated thyroid cancer (DTC). The study consisted of 93 patients diagnosed with DTC (79 females, 14 males) and 111 healthy control subjects (63 females, 48 males). The anthropometric measurements, lipid profiles, thyroid function tests and homeostatic model assessment (HOMA) as an indicator of insulin resistance (IR) of all patients were recorded. In addition IRS-1, IRS-2 and IGFBP-3 gene polymorphisms were determined by using polymerase chain reaction and restriction fragment length polymorphism. Hardy-Weinberg equilibrium was tested for each gene polymorphisms, and genetic effects were evaluated by the Chi Square test and multiple logistic regression. Homeostasis model assessment of insulin resistance (HOMA-IR), body mass index, waist circumference and serum total cholesterol levels were significantly higher in patients with DTC than in the control group. There was no difference between the two groups with respect to IRS-1, IRS-2 and IGFBP-3 gene polymorphisms. In addition, these gene polymorphisms were found to have no effect on lymph node metastases or tumor staging. While, obesity and increased HOMA-IR may be risk factors in DTC development, we suggest that IRS-1, IRS-2 and IGFBP-3 gene polymorphisms do not play an important role in pathogenesis of DTC.Öğe A Metabolic Syndrome Case Presenting with Lymphocytic Mastitis(Karger, 2012) Bilir, Betul Ekiz; Atile, Neslihan Soysal; Bilir, Bulent; Guldiken, Sibel; Tuncbilek, Nermin; Puyan, Fulya Oz; Sezer, AtakanBackground: Lymphocytic mastitis is a disease of premenopausal women, and its association with type 1 diabetes mellitus is the basis for its alternative name 'diabetic mastopathy'. It is a benign condition but must be considered in the differential diagnosis of breast cancer, especially in diabetic patients. Case Report: We present the case of an overweight 50-year-old dyslipidemic woman with metabolic syndrome presenting with lymphocytic mastitis. Conclusion: Although lymphocytic mastitis is usually regarded as an autoimmune disease seen mostly in diabetic patients, it may also be seen in nondiabetic patients with metabolic syndrome who do not have an autoimmune disease.Öğe Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study(Turkish Soc Radiology, 2023) Oktay, Aysenur; Aslan, Ozge; Taskin, Fusun; Tuncbilek, Nermin; Icten, Selma Gul Esen; Balci, Pinar; Aribal, Mustafa ErkinPURPOSE The clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions. METHODS This retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson's chi-squared test, the Fisher-Freeman-Halton test, and Fisher's exact test were used for the sta-tistical analyses. RESULTS The overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSION ADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision.Öğe Pleomorphic liposarcoma of the pectoralis major muscle in an elderly man: Report of a case and review of literature(Medknow Publications, 2009) Sezer, Atakan; Tuncbilek, Nermin; Usta, Ufuk; Cosar-Alas, Rusen; Cicin, IrfanPrimary liposarcoma of the pectoral major muscle is extremely rare. We report a case of liposarcoma of the pectoral major muscle which was treated with surgical excision and postoperative radiotherapy. A 70-year-old man admitted with left-sided painless progressively growing breast mass. Radiological investigation revealed liposarcoma of the pectoralis major muscle. The patient was treated by surgical removal. Pathological diagnosis was pleomorphic liposarcoma. The patient had postoperative radiotherapy and free of disease for 9 months. Surgical excision and postoperative radiotherapy is the most favored treatment strategy. Careful follow-up is mandatory for detecting recurrences.Öğe Prognostic value DCE-MRI parameters in predicting factor disease free survival and overall survival for breast cancer patients(Elsevier Ireland Ltd, 2012) Tuncbilek, Nermin; Tokatli, Fusun; Altaner, Semsi; Sezer, Atakan; Ture, Mevlut; Omurlu, Imran Kurt; Temizoz, OsmanPurpose: The aim of the study is to assess the predictive power of DCE-MRI semi-quantitative parameters during treatment of breast cancer, for disease-free (DFS) and overall survival (OS). Materials and methods: Forty-nine women (age range, 28-84 years; mean, 50.6 years) with breast cancer underwent dynamic contrast enhancement MRI at 1.0 T imaging, using 2D FLASH sequences. Time intensity curves (TICs) were obtained from the regions showing maximal enhancement in subtraction images. Semi-quantitative parameters (TICs; maximal relative enhancement within the first minute, E (max/1); maximal relative enhancement of the entire study, E-max; steepest slope of the contrast enhancement curve; and time to peak enhancement) derived from the DCE-MRI data. These parameters were then compared with presence of recurrence or metastasis, DFS and OS by using Cox regression (proportional hazards model) analysis, linear discriminant analysis. Results: The results from of the 49 patients enrolled into the survival analysis demonstrated that traditional prognostic parameters (tumor size and nodal metastasis) and semi-quantitative parameters (E-max/1, and steepest slope) demonstrated significant differences in survival intervals (p < 0.05). Further Cox regression (proportional hazards model) survival analysis revealed that semi-quantitative parameters contributed the greatest prediction of both DFS, OS in the resulting models (for E-max/1: p = 0.013, hazard ratio 1.022; for stepest slope: p = 0.004, hazard ratio 1.584). Conclusion: This study shows that DCE-MRI has utility predicting survival analysis with breast cancer patients. (C) 2011 Elsevier Ireland Ltd.

Contralateral breast cancer diagnosed within 12 months of the prior breast cancer is known as bilateral synchronous breast cancer. Bilateral, synchronous male breast cancer is extremely rare and consequently there are few publications describing imaging findings of synchronous bilateral male breast cancer. We aim to raise awareness about this rare entity by presenting the clinical and pathologic findings of a 64-year-old male case with synchronous bilateral breast cancer using multimodality imaging techniques including magnetic resonance imaging. Increasing awareness of the disease will prevent delays in diagnosis and treatment.Öğe The relationship between computed tomographic obstruction index and pulmonary vein cross-sectional area in acute pulmonary embolism(Springer-Verlag Italia Srl, 2020) Ustabasioglu, Fethi Emre; Solak, Serdar; Kula, Osman; Gunay, Burak; Serez, Bilkay; Tuncbilek, NerminPurpose To investigate whether the increased obstruction of the pulmonary arteries was associated with reduced pulmonary vein areas in acute pulmonary embolism (APE). Method We retrospectively analyzed a consecutive series of computed tomography pulmonary angiography studies of 107 patients with APE and 101 controls without APE between November 2010 and January 2019. The control and patient groups were compared with each other for differences between the mean cross-sectional areas of pulmonary veins. Further analysis was conducted by dividing the patient group into high-risk patients (>= 20%) and low-risk patients (< 20%) according to the pulmonary arterial obstruction index. The mean cross-sectional area of the pulmonary veins in these two groups was compared. Results The mean cross-sectional areas of the 4 pulmonary veins at the ostium level (CSAPV) were significantly lower for the patient group (mean: 102.6 mm(2)) compared with the control group (111.8 mm(2)) (p < 0.001). CSAPV cutoff value for determining the diagnosis of APE that maximized the accuracy was 109.12 mm(2) (AUC = 0.721; 95% CI 0.649-0.794); its sensitivity and specificity were 78.2% and 69.2%, respectively. CSAPV cutoff value for differentiating high-risk APE that maximized the accuracy was 102.6 mm(2) (AUC = 0.634; 95% CI 0.525-0.743); its sensitivity and specificity were 61.9% and 53.8%, respectively. Conclusions There is a negative correlation between the CSAPV and thrombotic material burden in the pulmonary arteries of patients with APE. Hence, the CSAPV can be used as a diagnostic tool in the evaluation of the presence and severity of pulmonary embolism.Öğe The Risk of Venous Thromboembolism With Thyroid Surgery(Lippincott Williams & Wilkins, 2010) Sezer, Atakan; Tuncbilek, Nermin; Gultiken, Sibel; Demir, Muzaffer; Irfanoglu, Mehmet Emin; Ibis, CemThe aim of the study is to assess preoperative risk of venous thromboembolism in thyroid surgery candidates and evaluate postoperative outcomes. This study was conducted on 116 consecutive patients between 2007 and 2008. The patients were classified by a Caprini venous thromboembolism risk assessment form in the preoperative period. The lower extremities of the patients were evaluated for deep venous thrombosis (DVT), by the same radiologist using color Doppler duplex ultrasonography, on preoperative day 1 and postoperative days 12 to 14. Venous diameter, venous wall response to compression, echogenity, thrombus within the lumen, loss of flow, and spectral wave changes were evaluated. Fifteen of the 116 patients withdrew from the study. The mortality rate was zero throughout the entire study. Eighty-seven (75.2%) patients were female and 29 patients (24.8%) were male. The mean age was 46.5 years (19-73 years). There were 18 patients in the very high risk group, 74 patients in the high risk group, and 24 patients in the moderate risk group in preoperative assessment. None of the patients had asymptomatic DVT preoperatively. All patients underwent thyroidectomy, and the average duration of hospitalization was 2.5 days (2 6 days). One (0.9%) patient with a risk score of 6 was diagnosed with asymptomatic DVT in the postoperative period with increased lumen diameter of the popliteal vein, thrombus, and lack of color flow in ultrasonography examination. Thyroid surgery may be a risk factor for developing DVT. In daily clinical practice, risk assessment should be done precisely to prevent venous thromboembolic events preoperatively in thyroid surgery.Öğe Scintigraphic findings in plant thorn tenosynovitis of finger(Lippincott Williams & Wilkins, 2008) Kaya, Meryem; Tuna, Hakan; Tuncbilek, Nermin; Cermik, Tevfik Fikret; Saridogan, KenanA 37-year-old women with pain and swelling in the third finger of the left hand for 10 months secondary to a plant-thorn injury in her garden is presented. Three-phase bone scintigraphy was subsequently requested after the results of plain radiography were reported as normal. Dynamic bone scintigraphy showed increased activity in the proximal phalanx on the 3 phases of the study. Magnetic resonance imaging described the inflammatory soft tissue formation around the third flexor tendon as tenosynovitis. Culture of biopsy material was negative, and the histology was consistent with chronic inflammatory changes.
