Hepatobiliary cystadenoma presenting with intermittent inferior vena caval obstruction

Hepatobiliary cystadenomas are rare benign tumours. They form as multilocular cysts in and around the liver. Their presentation is usually at a late stage when their size causes symptoms. We report a case of a 44-year-old woman presenting with abdominal pain, which was attributed to a multiloculate liver cyst. After intially refusing surgery she relented once intermittent inferior vena caval obstruction had developed. The cyst was found to be a hepatic cystadenoma.
