We report the case of a woman who presented with a typical picture of cholelithiasis and choledocholithiasis. A percutaneous transhepatic cholangiogram revealed instead a concentric narrowing of the common bile duct and at operation she was found to have a rare, benign tumor of the extrahepatic biliary tree, a granular cell schwannoma.
我们报告了一例表现为典型胆结石和胆总管结石症状的女性病例。然而，经皮经肝胆管造影显示胆总管呈同心性狭窄，手术时发现她患有肝外胆管树的一种罕见良性肿瘤——颗粒细胞型神经鞘瘤。
