We report a case of biliary cystadenoma in a 40 years female who prese
nted with an epigastric abdominal mass. The preoperative diagnosis was
made by means of US, CT and MRI. Lack of calcifications and the serol
ogical tests ruled out hydatid disease. Total excision by shelling out
the lesion from the liver parenchyma was performed. We recommend comp
lete surgical removal as the treatment of choice due to the malignant
potential and the high recurrence rate after partial resections.
