Hepatic tuberculosis mimics metastasis revealed by 18F-FDG PET/CT.

Extrapulmonary tuberculosis can affect almost any organ in the body. Here, we report a rare case of primary hepatic tuberculosis presented as multiple hepatic lesions and enlarged lymph nodes in the retroperitoneum and porta hepatis. PET/CT imaging showed avid FDG uptake by these lesions but did not find any definite primary malignancy. Finally, a diagnosis of primary hepatic tuberculosis was made with histopathologic examination.
