Abstract

Biliary cystadenoma of the liver is a rare multilocular cystic neoplasm of biliary origin. it occurs most often in middle aged women and rarely in children. Histogenesis of this tumor is uncertain. It may be developmental in origin arising from aberrant hamartomatous bile ducts or ectopic rests of embryonic biliary cystadenoma of the liver discovered at 8 month of intrauterine fetal life. This case supports its congenital theory.
