先天性胆总管囊肿合并胆道及肝胰病变的影像学诊断

The imaging diagnosis of complications of congenital choledochal cyst in bile duct,liver and pancreas

目的 探讨先天性胆总管囊肿(CCC)伴发胆道、肝脏及胰腺病变的影像学表现特征。 方法 回顾性分析经手术证实的47例CCC多普勒超声及CT表现,47例均行多普勒超声检查,CT扫描13例。 结果 CCC Ⅰ型29例,Ⅱ型3例,Ⅳ型9例,Ⅴ型6例;合并肝内外胆管结石13例,胆囊结石16例,胆囊炎18例,后位胆囊4例,囊肿穿孔3例,肝肿大18例,胰腺肿大17例。结论 CCC并发胆道系统结石、感染及肝胰损害机率较高,多普勒超声及CT检查不应仅满足于CCC的诊断,还应注意其合并病变。

Purpose To investigate the imaging appearances of complications of congenital choledochal cyst (CCC) in bile duct, liver and pancreas. Methods The appearances of Doppler ultrasonography and CT in 47 cases of CCC proved by pathology were reviewed retrospectively. All cases underwent Doppler ultrasonography and 12 cases underwent CT examination. Results The number of CCC were 29 cases of type Ⅰ ,3 cases of type Ⅱ ,9 cases of type Ⅳ ,and 6 cases of type V. The complications of CCC were 13 cases of duct stones inside or outside the liver, 16 cases of gallbladder stones, 18 cases of cholecystitis, 4 cases of back gallbladder, 3 cases of perforation of cyst, 18 cases of hepatomegaly and 17 cases of swelling of pancreas. Conclusion The frequence of complications of CCC is high in stone and infection of biliary system, and lesions of liver and pancreas. The examination of Doppler ultrasonography and CT should not only be settled for the diagnosis of CCC, but also for detecting its complications.
