肝内胆管细胞癌CT分型及临床意义

目的 探讨肝内胆管细胞癌(ICC)的形态学CT分型及临床意义.方法 回顾性分析经临床病理证实的22例ICC的CT表现,依据肿瘤的形态特征对ICC分型.结果 22例肿瘤患者中:肿块型9例,表现为肝内结节状肿瘤,不伴周围胆管扩张;管周浸润型4例,表现为沿胆管纵轴生长的树枝状肿瘤,伴周围胆管扩张;管内生长型2例,表现为单发或多发肿瘤结节位于扩张的胆管内;肿块并管周浸润型7例,表现为肝内结节状肿瘤,伴周围胆管扩张.结论 不同形态类型ICC的CT表现不同.CT检查能够对ICC进行准确形态学分型,对临床选择合理的治疗方案及判断预后具有重要意义.

Clinical significance of CT classification of intrahepatic cholangiocarcinoma

Objective To discuss the morphologic CT classification and clinical significance of intrahepatic cholangiocarcinomas (ICC). Methods The CT manifestations of 22 patients with ICC confirmed by pathology were reviewed retrospectively, and the types of ICC were determined according to morphologic characteristics of tumors. Results ICCs in 22 patients were classified into four types: mass-forming type (n=9), a nodular mass in the liver parenchyma without dilatation of the peripheral ducts; periductal-infiltrating type (n=4), extended longitudinally along the bile duct and formed a branchlike mass with dilatation of the peripheral ducts; intraductal growth type (n=2), a single or multiple papillary masses within the dilated duct; mass-forming plus periductal-infiltrating type (n=7), a nodular mass in the liver parenchyma with dilatation of the peripheral ducts. Conclusion CT findings of the different morphologic types of ICC are of certain characteristics. CT scan can accurately determine the morphologic types of ICC, which is useful for choosing the appropriate treatment and predicting prognosis.
