title: Congenital extra-hepatic biliary cyst in a Congo African Grey Parrot (Psittacus erithacus erithacus).
abstract: An 8-week-old Congo African Grey Parrot (Psittacus erithacus erithacus) was presented with a history of abdominal enlargement since hatch. Trans-illumination of the abdomen suggested that the enlargement was due to marked hepatomegaly. This was supported by radiographic and ultrasonic examination. Postmortem examination revealed an extra-hepatic biliary cyst 4 cm in diameter.
