The biliary cystadenoma (BC) is a rare tumor of the biliary tract characterized by multi-locus cysts recovered by cuboid or non-lashed columnar epithelium and its differential diagnosis with others cystic lesions of the liver is very difficult. The radiological methods like ultrasound, computed tomography and magnetic resonance don’t get differentiated BC to bile duct carcinoma or cystadenocarcinoma. The treatment of choice of BC is the complete resection due the possibility of malignant degeneration. This paper presents a case of a 49 years-old woman with a palpable mass in the epigastrium and fever about one month. The computed tomography of abdomen shows the multilocular cystic lesion with internal septa occupating all the left lateral segment of the liver. The left lateral segmentectomy was carried out with good post-operative evolution and the histopathology shows BC without mesenquymal stroma. The BC in almost cases are asymptomatic however, it may course with fever, jaundice, abdominal pain and palpable mass. The treatment of choice is the total surgical resection because is difficult its differential diagnosis with bile duct carcinoma or cystadenocarcinoma. In conclusion, the patients with cystic lesions of the liver with internal septa in the cysts with fever, jaundice or abdominal pain must be treated with liver resection.
