F-18 FDG PET/CT imaging of tuberculous lymphadenopathy mimicking lymphoma: a case report

We report a case of pulmonary tuberculous lymphadenopathy in an asymptomatic 19-year-old female. Thoracic computed tomography [CT] scan showed enlargement of lymph nodes in right neck, mediastinum and left hilum with heterogeneous contrast enhancement. Positron emission tomography [PET] / CT with F-18-fluorodeoxyglucose [F-18-FDG] demonstrated significantly increased metabolic activity of the lymph nodes. The lesions were diagnosed as tuberculous lymphadenopathy by histopathologic examination
