Özet
Çalışmamızın amacı toraks bilgisayarlı tomografisinde görülen mediastinal lenf nodlarının boyut, lokalizasyon, sayı, boyanma paterni ve parankim yapısını değerlendirerek etiyolojiyi saptamadaki etkinliğini ortaya çıkarmaktır. Çalışma kapsamına, toraks bilgisayarlı tomografi incelemesi yapılan ve mediastinal lenf nodu saptanan 73'ü erkek, 23'ü kadın 96 olgu alındı. Olguların 70'i malign proçeslere (akciğer kanseri, lenfoma veya akciğer dışı maligniteler ) 26'sı benign proçeslere (tüberküloz, sarkoidoz, atipik pnömoni ) bağlı olarak lenfadenopati tespit edilen hastalardı. Mediastinal lenf nodları yerleşim, sayı, boyut, kontrastlanma paterni, kalsifikasyon veya nekroz içermeleri ve pake oluşumu özellikleri yönünden değerlendirmeye alındı. Lenf nodu kalsifikasyonu yönüyle karşılaştırıldığında lenfoma olguları ile akciğer kanserli ve tüberkülozlu olgular arasında istatistiksel olarak anlamlı farklılık bulundu (p<0.05). Kontrastlanma paternlerine göre karşılaştırıldığında akciğer kanseri ile infeksiyöz-inflamatuvar proçeslere bağlı lenfadenopatiler arasında istatistiksel olarak anlamlı farklılık saptandı (p<0.05). Akciğer kanseri ve tüberküloz olguları mediastinal lenfadenopati boyutları açısından karşılaştırıldığında aralarında istatistiksel olarak anlamlı farklılık saptandı (p<0.05). Mediastinal lenfadenopatilerde nekroz varlığı yönünden akciğer kanseri olguları ile tüberküloz olguları ve infeksiyöz-inflamatuvar proçeslere sahip olgular karşılaştırıldığında istatistiksel olarak anlamlı farklılık bulundu (p<0.05). Çalışmamızda heterojen kontrastlanma paterninin metastatik lenfadenopatilere, homojen kontrastlanma paterninin benignitelere, periferik kontrastlanma paterninin tüberküloz veya malignitelere bağlı olduğunu, kalsifikasyon varlığının öncelikle tüberkülozu; nekroz varlığının maligniteleri (akciğer kanseri ve lenfoma) işaret ettiğini saptadık. Anahtar kelimeler: mediasten, lenfadenopati, bilgisayarlı tomografi
The aim of our study is to show the efficiency of revealing the etiology by evaluating the dimension, location, number, enhancing pattern and the structure of parenchyma of the mediastinal lymphadenopathy detected with thoracic computed tomography. Ninetysix cases, 73 men and 23 women that were detected with mediastinal lymphadenopathy after the torax computed tomography examination were taken into study. Seventy of them with malign processes (lung cancer, lymphoma or extrathoracic malignancies), and the other 26 with benign processes (tuberculosis, sarcoidosis and pneumonia) were the lymphadenopathy detected cases. Mediastinal lymphadenopathy were evaluated considering their location, dimension, conglomeration and whether they included calcification or necrosis. When compared lymphoma, lung cancer and tuberculosis cases according to lymphadenopathy calcification; there was statisticaly significant difference between them (p<0.05). Lymphadenopathy associated with infectious or inflammatory processes and lung cancer cases when compared to their contrast patterns, statistical significant difference was determined (p<0.05). The lung cancer cases and tuberculosis cases when compared with their dimensions of mediastinal lymphadenopathy, statistical significant difference was found (p<0.05). There is also a statistical significant difference when lung cancer, tuberculosis and infectious or inflammatory process cases are compared with the presence of necrosis in lymphadenopathy (p<0.05). In our study, we have determined that heterogenous enhancement patterns are related to the metastatic lymphadenopathy; homogenous enhancement patterns to benignities; and peripheral enhancement patterns to tuberculosis or malignancies, and the presence of calcification firstly points out tuberculosis while necrosis points out malignancies (lung cancer and lymphoma). Key words: mediastinum, lymphadenopathy, computed tomography
