Isolated hepatobiliary tuberculosis: a diagnostic challenge

Hepatobiliary system involvement is frequently seen as part of disseminated tubercular infection. But primary isolated hepatobiliary tuberculosis with no evidence of tuberculosis elsewhere in the body is extremely rare. Isolated hepatobiliary tuberculosis can cause diagnostic dilemma as the clinical, laboratory and imaging features are non-specific in majority of the cases. We report the case of a 50-year-old woman who presented with hepatobiliary tuberculosis with no pulmonary or extra hepatic involvement. Liver function tests were abnormal and ultrasonography (USG), CT and MR cholangiopancreatography showed multiple focal lesions in the liver. The diagnosis of tuberculosis was confirmed by a USG-guided biopsy of the liver lesions. In endemic regions with the presence of supportive imaging findings, in the appropriate clinical setting, the possibility of hepatic tuberculosis should be considered and diagnosis has to be confirmed with histopathological examination.
