A large stone detected in Roux-en-Y jejunal limb 20 years after excision of congenital choledochal cyst.

摘要

A 30-year-old woman was transferred to our hospital with pain in the right hypochondriac region. The patient had undergone excision of an extrahepatic cyst and Roux-en-Y reconstruction for a congenital choledochal cyst (Todani type IVA) at 10 years of age. A magnetic resonance imaging scan demonstrated scattered tiny stones in the dilated intra-hepatic bile duct. In addition, a huge low-intensity, oval-shaped mass approximately 8 cm in diameter was also detected in the dilated jejunal limb (Fig 1). Percutaneous transhepatic biliary drainage was performed for cholangitis; bile cultures were positive for Klebsiella. Serum tumor markers were within normal limits.
