Utility of Magnetic Resonance Cholangiopancreatography for the Diagnosis of Cholangiocarcinoma in a Patient with Situs Inversus / 대한소화기내시경학회지

ABSTRACT

Situs inversus is a rare condition with genetic predisposition and is characterized by transposition of both heart and intra-abdominal viscera to the opposite side of the body. Cholangiocarcinoma in this condition has rarely been reported. We present a case of adenocarcinoma of the common hepatic duct proximal to the cystic duct in a 68-year-old male with total situs inversus. The patient presented with complaints of abdominal pain, intermittent fever and chilling sensation without jaundice. Magnetic resonance cholangiopancreatography prior to surgery demonstrated segmental narrowing of the common hepatic duct proximal to the cystic duct and two stones in the proximal portion of the narrowed segment. Open laparotomy was performed to remove the lesion. Cholangiocarcinoma was confirmed pathologically. Magnetic resonance cholangiopancreatography was the only pre-operative diagnostic method which had suggested malignancy in this case.
