Tuberculous Lymphadenitis Which Mimicked Mediastinal Tumor And Elevated Fdg Uptake At Pet-Bt

Tuberculosis remains to be a serious public health problem in our country and all over the world. Extrapulmonary tuberculosis causes major clinical problems because of difficulties encountered in the differential diagnosis. In this case report, we aimed to discuss a case of tuberculous lymphadenitis mimicking mediastinal tumor in chest CT and PET-CT examination. Eighty years old female patient with right paratracheal enlargement in the chest radiography was admitted to our hospital. Thorax CT and MR imaging was supporting this expansion as concordant with the mediastinal tumor. The PETCT showed increased FDG uptake in favor of malignant masses. However, mediastinoscopic biopsy was reported as tuberculous lymphadenitis and antituberculous therapy was started. It should be kept in mind that even in adults patients, tuberculous lymphadenitis should be thought in differential diagnosis of mediastinal masses suspecting malignancy with imaging techniques and also it should not be forgotten that tuberculous lymphadenitis may be presented with elevated FDG uptake at PET-BT.
