摘要
目的:分析肝门部管壁浸润型胆管癌的多层螺旋CT(MDCT)表现。方法:回顾性分析12例肝门部管壁浸润型胆管癌的MDCT表现,所有病例均经手术病理及临床综合诊断证实,12例均行CT平扫及三期增强扫描,3例行延迟扫描。结果:12例CT平扫均显示胆系梗阻征象,梗阻平面位于肝门区,强化扫描12例均显示肝门部胆管走行区结节灶或环状肿物,病变于动脉期明显均匀强化,门静脉期强化达峰值,平衡期其密度略低于门静脉期,3例延迟扫描病例未见延迟强化。结论:肝门部管壁浸润型胆管癌的MDCT表现有一定特征。
Objective： To explore the multidetector computed tomography （MDCT） features of infiltrating hilar cholangiocareinoma （ISHCC）. Methods：The MDCT findings in 12 patients with clinically proved ISHCC were retrospectivdy analyzed. All cases underwent plain and tri-phase enhanced CT scanning, 3 cases underwent delayed CT scanning. Results：On plain CT images, all of the 12 cases showed hilar biliary obstruction. On enhanced CT images, all cases showed a small nodular or collar like hyperdense mass on hepatic artery phase, the re.ass reached its maximum density on portal venous phase, on hepatic parenchymal phase, its density was slightly lower than that on portal venous phase, no late contrast enhancement were seen on 3 delayed CT scanning cases. Concluslon：To same extent, the MDCT features of ISHCC have some characteristics.
