Hilar biliary cystadenocarcinoma: an uncommon hepatic neoplasm.

ABSTRACT

Biliary cystadenocarcinoma (BCAC) is a rare cystic tumour of the liver; with its benign counterpart, it accounts for <5% of non-parasitic hepatic cysts. Preoperative diagnosis of BCAC is difficult; complete surgical excision is recommended to prevent recurrence or metastasis. We present the case of a 67-year-female with centrally located BCAC involving the right hepatic duct and distorting the hepatic hilum. This report highlights the difficulties in diagnosis, surgical resection, subsequent biliary reconstruction and its outcome.
