ABSTRACT
@#Biliary cystic tumors (BCT), which include the subgroups biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC), affect 5 to 10% of the global population. BCTs are solitary, multiloculated cysts that are usually intrahepatic in location. BCACs are rare tumors that arise from the malignant transformation of BCA. The presentation of BCT often mimics simple hepatic cysts and other hepatic cystic lesions making diagnosis difficult. With the recent advances in medical imaging, BCTs have been diagnosed more often. Patients with BCT are often asymptomatic. When symptoms are present, however, patients usually manifest with abdominal pain and distention. Given the high risk of recurrence, complete surgical resection by formal hepatic resection or enucleation is the best treatment of choice for patients. We present a case of a 65-year-old female who came in due to a four-year history of an enlarging abdomen. She was initially treated, preoperatively, as a case of ovarian new growth but was later managed as hepatic cystadenocarcinoma.
