[Hemobilia caused by biliary cyst].

Recurrent angiocholitis attacks occurred in an 80-year-old woman, and repeated investigations could not provide any diagnosis. Subsequently, the patient developed haematemesis. Angiography revealed haemobilia from an intrahepatic cause. Surgical constatations and pathological examination of the resected specimen revealed that haemobilia was due to a non-parasitic cyst of the liver. In this case, haemobilia resulted from two unusual complications of this hepatic lesion: intra-cystic bleeding and communication with an intrahepatic duct. Haemobilia has never been reported as a complication of non-parasitic cyst of the liver.
