Spiral CT diagnosis of intrahepatic peripheral cholangiocarcinoma
肝内周围型胆管细胞癌的螺旋CT诊断

摘要

目的 探讨螺旋CT在肝内周围型胆管细胞癌诊断中的价值。方法 本研究于2020年5月－2021年5月期间选择我院收治的22例周围型肝内胆管细胞癌患者作为主要分析对象，患者均接受螺旋CT诊断，收集所有患者的临床资料及影像资料进行回顾性分析。结果 22例患者接受螺旋CT扫描后，病灶的平扫结果均表现为低密度，并且病灶内及其周围胆管存在扩张现象，其中胆管结石、动脉期增强扫描病灶边缘少量增加、门静脉期中央网格样提高、延迟期增强的患者分别有2例、7例、6例、17例，分别占比（9.09%）、（31.82%）、（27.27%）、（77.27%）；密度与一般肝实质相比有增加趋势，且肝叶局限性萎缩的患者有8例，占比（36.36%）。结论 在对肝内周围型胆管细胞癌采用CT诊断时，其重要的征象有肝叶局限性萎缩、病灶延迟期增强、病灶内胆管或病灶周围胆管扩张。其在病情的诊断中具有重要作用。

Abstract

Objective: To explore the value of spiral CT in the diagnosis of intrahepatic peripheral cholangiocarcinoma.
Methods: From May 2020 to May 2021, 22 patients with peripheral intrahepatic cholangiocarcinoma admitted to our hospital were selected as the main analysis objects in this study. The patients were diagnosed by spiral CT, and the clinical data and images of all patients were collected. The data is analyzed retrospectively.
Results: After 22 patients underwent spiral CT scan, the plain scan results of the lesions showed low density, and the bile ducts in and around the lesions were dilated. Among them, bile duct stones, arterial phase enhanced scan, the edge of the lesion increased slightly, and the central network of portal vein phase There were 2 cases, 7 cases, 6 cases, and 17 cases of patients with improved pattern and delayed phase enhancement, respectively, accounting for (9.09%), (31.82%), (27.27%), (77.27%); density and normal liver There is an increasing trend compared to the real substance, and there are 8 patients with localized hepatic lobe atrophy, accounting for 36.36%.
Conclusion  : In the diagnosis of intrahepatic peripheral cholangiocarcinoma by CT, the important signs include localized atrophy of the liver lobe, enhancement of the delayed stage of the lesion, and dilatation of the bile duct in the lesion or around the lesion. It plays an important role in the diagnosis of the disease.
