Abstract

Hepatic tuberculosis is usually associated with active pulmonary or miliary tuberculosis. The occurrence of an isolated hepatic mass-forming tuberculosis with no evidence of tuberculosis elsewhere is rare. We report a case of a 31-year-old male with a solitary hepatic granuloma mimicking a mass-forming intrahepatic cholangiocarcinoma. Ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography of the abdomen showed a malignant tumor-like lesion. We then conducted endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) for confirmation of the hepatic hilar mass, which was found to be a hepatic tuberculosis granuloma as the final diagnosis.
