[Cystic lymphangioma of the liver. Presentation of a clinical case].

The cystic lymphangioma of the liver is an extremely rare benign tumor that usually belongs to a systemic lymphangiomatosis. A case of an adult woman presenting a cystic lymphangioma as single hepatic lesion with no other viscera affected is described. Ultrasonography and computed tomography did not allow a differential diagnosis of the lesion from the more common hydatid cyst. Definitive diagnosis and treatment were reached only by exploratory laparotomy.
