目的探讨CT和MRI在Caroli病诊断中的价值。方法对经组织病理学证实的10例Caroli病的CT和MRI资料进行回顾性分析。全部病例行CT平扫及增强扫描,其中5例另行MRI检查,分别采用Flash2DT1WI(TR/TE148/4ms),真实稳态快速梯度回波(TrueFisp)T2WI(TR/TE5·8/2·9ms),MRCP胰胆管水成像(TR/TE1120/86ms)序列扫描。结果本组10例Caroli病的肝内胆管均呈节段性扩张,表现为多发囊状/柱状影;囊状影与轻度扩张的柱状小胆管影及囊状影之间相连通,CT能部分显示此征像,MRITrueFisp及MRCP序列可全面直接显示该征象,无需增强扫描;本组4例属Ⅰ型,均伴有肝内胆管结石,无合并肝硬化及门脉高压征;6例属Ⅱ型,均合并肝硬化及门脉高压征,其中4例无肝内胆管结石,2例合并肝内胆管结石;3例合并双侧海绵肾,2例属Ⅱ型,1例属Ⅰ型。结论CT/MRI能对Caroli病做出明确诊断,且MRI较CT更为优越。
Objective To investigate the value of CT and MRI in the diagnosis of Caroli disease. Methods The CT and MRI data of 10 cases of Caroli confirmed by histopathology were analyzed retrospectively. CT scan and enhanced scan were performed in all cases. Five of them were examined by MRI, and the results were compared with those of TrueFisp T2WI (TR / TE5.8 / 2 · 9ms) using Flash2DT1WI (TR / TE148 / , MRCP cholangiopancreatography (TR / TE1120 / 86ms) sequence scan. Results The group of 10 cases of Caroli disease intrahepatic bile duct were segmental expansion, the performance of multiple cystic / columnar shadow; Cystic shadow and slightly dilated columnar small bile duct shadow and cystic shadow connected, CT Part of the display of this sign, MRITrueFisp and MRCP sequence can be a complete and direct display of this sign without the need for enhanced scanning; 4 cases of this group are type I, are associated with intrahepatic bile duct stones, no complications of cirrhosis and portal hypertension; 6 cases Ⅱ type, were complicated by cirrhosis and portal hypertension, 4 cases without intrahepatic bile duct stones, 2 cases with intrahepatic bile duct stones; 3 cases with bilateral sponge kidney, 2 cases are type Ⅱ, 1 case is genotype Ⅰ. Conclusion CT / MRI can make a definite diagnosis of Caroli disease, and MRI is superior to CT.
