    Computed Tomographic and Magnetic Resonance Imaging Findings of Asymptomatic Intra-Abdominal Gastrointestinal System Lipomas
    (Lippincott Williams & Wilkins, 2008) Genchellac, Hakan; Demir, Mustafa K.; Ozdemir, Huseyin; Unlu, Ercument; Temizoz, Osman
    Lipomas are common benign mesenchymal neoplasms documented in literature. This study aimed to describe the computed tomographic (CT) and magnetic resonance imaging (MRI) findings of gastrointestinal system lipomas, all of which are incidentally found in routine abdominal imaging studies. Lipomas were depicted as homogeneous, nonenhancing, well-marginated lesions consistent with adipose tissue on CT and MRI The density measurements on CT images consistent with fat are virtually diagnostic. Lipomas can incidentally be found and should be considered in the differential diagnosis of soft tissue gastrointestinal system-related masses. Computed tomographic or MRI examinations can correctly diagnose a lipoma nonoperatively, thereby allowing better treatment planning..

    Two-detector Computed Tomography Map of the Inferior Epigastric Vessels for Percutaneous Transabdominal Intervention Procedures
    (2014) Gençhellaç, Hakan; Dursun, Memduh; Temizöz, Osman; Çağlı, Bekir; Demir, Mustafa K.
    Background:It is crucial to know anatomic variations and the exact course of an inferior epigastric artery (IEA) to prevent any complica-tions during percutaneous abdominal interventions. Aims:The aim of this study was to map the inferior epigastric ves-sels using reconstructed two-detector computed tomography images and measure the distance from the inferior epigastric artery (IEA) to the midline to determine a safe route for percutaneous abdominal interventions. Study Design: Retrospective comparative study.Methods:Coronal reconstructed two-detector computed tomogra-phy images of 200 patients were evaluated to measure the distances between the IEA and midline at three levels (origin, middle, and dis-tal). Vein and artery arrangements were documented.Results:The most frequently encountered arrangement (41.5%) was a single vein and artery on both sides. Mean distances on the right and left sides were 4.01 and 4.47 cm at the umbilical level, 3.81 and 4.26 cm at the midlevel, and 5.62 and 5.51 cm at the origin level. On both sides, measurement differences between the three levels were highlysignificant (p<0.05). In addition, a total of 56 IEA bifurcations were depicted in all 200 patients. Thirteen of the 56 bifurcations occurredonly on the right side, 11 only on the left side, and 32 on both sides.Conclusion:It is important to be attentive to the IEA's course, at different midline levels, when attempting percutaneous interventions via an abdominal approach.
