Biliary cystadenoma is a very uncommon benign cystic neoplasm involving the liver and the biliary tract. Most common presentations include right upper quadrant pain, nausea, vomiting, obstructive jaundice, and enlarging liver size. It can mimic many more commonly occurring diseases such as hepatic cyst, hepatic abscess, hydatid disease of the liver, and hepatic tuberculosis. Hence it becomes very challenging for physicians to correctly diagnose it due to its rarity and similarity with other conditions. Furthermore, very few pieces of literature guide physicians in correctly identifying the disease. Based on his physical examination and detailed investigation, we present a case report of a 72-year-old female diagnosed with biliary cystadenoma. We hope that this case report will significantly add to the existing literature on this subject.
