Abstract

Extrahepatic duct duplication is an extremely rare congenital anomaly. Hilar cholangiocarcinoma with extrahepatic bile duct duplication was reported; however, intraductal papillary neoplasm of the bile duct (IPNB) with extrahepatic bile duct duplication has not been reported to the best of our knowledge. We report a rare case of IPNB with extrahepatic bile duct duplication of a 64-year-old female. The patient underwent extended right hepatectomy, and the results of a subsequence histopathological examination were consistent with an IPNB with extrahepatic bile duct duplication. We report this rare case with radiologic imaging findings and a brief review of the current literature.

이중 담관 기형은 매우 드문 선천 기형의 한 종류이다. 이중 담관 기형과 동반한 담관암의 증례가 보고된 적이 있으나 담관암의 전 침습적 병변인 관내 유두종이 이중 담관 기형과 함께 동반한 증례는 보고된 적이 없다. 우리는 64세 여성에게서 발견된 이중 담관 기형과 동반된 관내 유두종을 보고하고자 한다. 환자는 간 우엽 절제술을 시행하였으며 병리 결과에서 관내 유두종, 이중 담관 기형으로 진단되었다. 이에 대한 증례를 간단한 문헌 고찰과 함께 보고한다.
