Primary hepatic tuberculosis is a rare manifestation of extra-pulmonary tuberculosis even in highly endemic countries. The incidence of hepatic tuberculosis has increased in the recent years due to high prevalence of HIV/AIDS. Radiological imaging is an important tool for making the diagnosis, but often the imaging findings are non-specific and may mimic other benign or malignant hepatic diseases. We report a case of 54-year-old woman who was detected to have hepatic mass on radiological imaging which was misdiagnosed as hydatid cyst. Intraoperatively, the characteristic features of hydatid cyst were absent. A partial resection of this cystic mass was performed. Histopathological examination of the resected specimen revealed granulomatous inflammation consisting of histiocytes and Langhans-type giant cells surrounded by lymphocytes suggestive of hepatic tuberculosis. The patient was administered antitubercular therapy for 1 year. Repeat imaging on follow up showed disappearance of the hepatic lesion.
