巨囊型肝内胆管囊腺类肿瘤的MSCT诊断

目的:探讨巨囊型肝内胆管囊腺类肿瘤的MSCT特点,评价其诊断价值。方法:回顾性分析经手术病理证实的4例胆管囊腺瘤及2例胆管囊腺癌的MSCT表现,包括病灶位置、囊液密度均匀度、有无分隔、壁结节、强化特征、邻近肝内囊性病灶、肝内胆管扩张情况及邻近肝实质灌注等。结果:6例均表现为囊性病灶,5例病灶位于近肝门部,1例病灶位于肝右叶下段;4例病灶囊液密度均匀,2例囊液密度不均匀;5例病灶囊内均有分隔,1例病灶无分隔;2例病灶存在附壁结节并明显强化,2例病灶囊壁及分隔钙化;2例病灶邻近肝内可见小囊状病灶(1~2个);5例病灶远肝门侧肝内胆管轻度扩张,1例肝内胆管未见扩张;5例病灶周围肝实质动脉期异常灌注。结论:巨囊型肝内胆管囊腺类肿瘤MSCT表现具有特征性,对诊断、鉴别诊断及指导临床治疗均有较大价值。

MSCT Diagnosis of Giant Cystic Intrahepatic Bile Duct Cystadenomatous Tumor

Objective: To explore the MSCT class features of giant cystic intrahepatic bile duct cystadenomatous tumor, and to evaluate the diagnostic value. Methods: Retrospective analysis MSCT performance of 4 cases of cystadenoma and 2 cases of cystadenocarcinoma of biliary which had been proved by operation pathology, including the location of the lesion, cyst fluid density uniformity, without separation or not, mural nodules and enhancement features, adjacent liver within cystic lesions, dilatation of intrahepatic bile duct and the perfusion of adjacent liver parenchyma. Results: All of 6 cases were cystic, 5 cases near the hilar, 1 case of in under the posterior lobe of liver; 4 cases' hydatid fluid were uniformity, but two cases were not; 5 cases were discretely intracapsular, 1 case not; 2 cases had mural nodules and enhanced significantly, 2 cases separate and wall calcification; 2 cases with of liver small cystic(1-2) near lesions; 5 cases' intrahepatic bile duct were dilated far side of the hilar, 1 case not; 5 cases' surrounding liver parenchyma were abnormal perfusion in the arterial lesions. Conclusion: The MSCT performancegiant of cystic intrahepatic bile duct cystadenomatous tumor with a characteristic have a greater value of the diagnosis, differential diagnosis and clinical treatment.
