Type II choledochal cysts are rare congenital malformations of the biliary ductal system. We report a case in which a type II choledochal cyst presented as a mass in the porta hepatis without any demonstrable connection with the biliary tree. In the English literature, this is the first described case of this type in the absence of biliary tract malignancy. We hypothesize that the connection to the biliary tree was lost by either torsion of the cyst or fibrosis due to chronic inflammation.
II 型胆总管囊肿是胆管系统罕见的先天性畸形。我们报告一例 II 型胆总管囊肿表现为肝门部肿块，且与胆管树无明显连接的病例。在英文文献中，这是首例报道的无胆道恶性肿瘤的此类病例。我们推测囊肿扭转或慢性炎症导致的纤维化使囊肿与胆管树的连接消失。
