目的评价MRCP在先天性胆管扩张症诊断中的重要价值。方法对24例经手术或病理证实的先天性胆管扩张症的MRCP进行回顾性分析。结果按Todami五分法,24例先天性胆管扩张的MRCP表现如下:(1)I型:肝外胆管囊肿17例,表现为肝外胆管囊状或梭形扩张,(2)IV型:肝内外胆管多发性囊肿5例,表现为肝内外胆管多发囊状或梭形扩张,(3)V型:即Caroli氏病2例,表现为肝脏内胆管多发大小不一囊状或“串珠状”扩张。24例均伴有胆管、胆囊炎,12例伴有胆囊、胆管结石。结论先天性胆管扩张症的MRCP表现特征具有十分可靠的定性价值。
Objective To evaluate the value of MRCP in the diagnosis of congenital bile duct dilatation. Methods Retrospective analysis of MRCP in 24 cases of congenital bile duct dilatation confirmed by surgery or pathology. Results Todami five-point method, 24 cases of congenital bile duct dilatation of the MRCP performance are as follows: (1) Type I: 17 cases of extrahepatic bile duct cysts, showed extrahepatic bile duct cystic or spindle expansion, (2) Type IV: liver Internal and external bile duct multiple cysts in 5 cases, manifested as multiple intrahepatic bile duct cystic or fusiform expansion, (3) V type: Caroli’s disease in 2 cases, showed multiple intrahepatic bile duct cysts or “beaded ”expansion. 24 cases were associated with bile duct, cholecystitis, 12 cases associated with gallbladder, bile duct stones. Conclusion MRCP features of congenital bile duct dilatation have very reliable qualitative value.
