摘　　要：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 study the value of CT and MRI in diagnosis of Caroh disease. Methods CT and MR findings in 10 patients with histologically proved Caroli disease were retrospectively reviewed. All the patients underwent both liver plane CT and contrast - enhanced CT. Five of 10 patients underwent MR imaging with Flash 2D T1WI（TR/TE 148/4ms）, True Fisp T2WI（TR/TE 5.8/2.9ms） and MRCP（TR/IE 1120/86ms）sequences. Results The imaging paremeters of Caroli disease were multiple saccular/columnar dilatation of intrahepatic bihary ducts and communication with each other, which only partly were depicted at CT, however, all imaging findings were depicted at MRI True Fisp and MRCP without contrust - enhanced scanning. Of 10 patients, 4 cases were type Ⅰ of Caroh disease with hepatolith, but without hepatic cirrhosis and portal hypertention; 6 cases type Ⅱ ,all complicated with hepatic cirrhosis and portal hypertension. Of 6 patients with type Ⅱ Caroh disease, 4 cases had not hepatolith, and 2 cases had hepatohth. Of 10 patients, 3 cases had bilateral sponge kidney. Conlusion Caroh disease could be identified by CT or MRI, but MRI was suoerior to CT in deoicting Caroli disease.
