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.

간결핵은 주로 폐결핵이나 속립성 결핵에 동반된 형태로 나타난다. 다른 부위에 결핵 감염 없이 일차성으로 간결핵으로 발현하는 경우는 드물다. 간 내 담관암 양상으로 보이는 간 종괴를 주소로 내원한 31세 남자의 증례이다. 복부 초음파, 전산화 단층 촬영, 자기공명영상, 양전자 단층 촬영에서 악성 종양을 의심할 만한 소견을 보이고 있었다. 복부 초음파를 이용한 조직 검사에서 진단이 불분명하여 내시경 초음파 검사와 내시경 초음파 세침흡인생검을 이용하여 간문부 결핵성 육아종을 진단한 증례이다.
