MRI Findings in Biliary Cystadenoma

Abstract

Biliary cystadenoma is a rare cystic hepatic neoplasm. We herein present a 44 year-old female patient with biliary cystadenoma focusing on difficulties in diagnosis because of lack of specific findings with imaging, and the need for surgery. As biliary cystadenomas have high recurrence risks and malignant transformation potential, careful follow-up should not be underestimated. Proper surgical resection of the lesion may be considered the most suitable diagnostic and therapeutic procedure, and prognosis is generally excellent after removal of the tumor.
