Isolated Tuberculosis of Gallbladder: Case Report of a Rare Disease with the Review of Literature

Tuberculosis of the gallbladder is an extremely rare entity with only few case reports in the literature. Gallbladder tuberculosis is often found in association with gallstones or cystic duct obstruction and it may be a part of miliary tuberculosis, abdominal tuberculosis, primary isolated gallbladder tuberculosis and as acalculous cholecystitis in immunocmpromised patients. Preoperative diagnosis of gallbladder tuberculosis is very difficult as non of the clinical signs, symptoms and radiological findings are pathognomonic. Histopathology confirms the diagnosis. Herein, we are presenting a case of 48 years female who presented with recurrent right upper abdominal pain associated with nausea and vomiting for eight months. Following ultrasonographic findings of calculous cholecystitis, exploratory laparotomy was done. Gall bladder was densely adherent to liver bed and the wall was thickened mimicking carcinoma. Histopathological examination confirmed the diagnosis of gall bladder tuberculosis. We are presenting this case because of its rarity and simulation with malignancy.
