The advancement of radiological investigations has led to the early and incidental detection of hepatic cystic lesions. These are most commonly the simple cysts but can be malignant as well. Despite the recent advances, these lesions still pose a diagnostic as well as therapeutic challenge. The biliary cystadenomas and carcinomas form around 5% of all the malignant cystic lesions of liver. These lesions are hardly diagnosed preoperatively and are usually a histopathological surprise. They warrant a surgical excision. Herewith, the authors are describing a case of cystic hepatic neoplasm initially misdiagnosed as hydatid cyst of liver and discovered to be a vascular cystic lesion intraoperatively. This patient underwent resection of the lesion and was discovered to harbour biliary cystadenoma on histopathological specimen.
