Spontaneous rupture of hepatobiliary cystadenoma: a case report.

Hepatobiliary cystadenoma is a rare hepatic neoplasm which has a high tendency to recur and has malignant potential. We review the literature and report a case of intrahepatic cystadenoma presenting with abdominal pain and ascites following spontaneous rupture. Complete excision of the tumor offers the best chance of cure and avoids recurrence, secondary infection or malignant change.
