摘　　要：目的探讨肝脏疾病致肝内淋巴淤滞的CT特点及相关病理学特征。方法回顾性分析了36例均CT增强双期扫描肝癌、肝硬化、肝转移瘤、肝炎及肝挫伤所致肝内淋巴淤滞的CT表现与临床资料,并探讨其发生机制。结果CT增强后均有范围不等门静脉分支和/或肝内下腔静脉周围线条状或环形线状低密度影,呈伴随血管“晕征”。结论肝内淋巴淤滞的CT表现有其特征性,CT对本病的诊断有重要价值。Objective To explore the characteristics of CT image and pathological changes of intrahepatic lymphatic stasis （ ILS ） caused by hepatic diseases . Methods Clinical data and CT images in contrast - enhanced arterial phase and portal venous phase in 36 cases with ILS saused by hepatic cancer, cirrhosis,hepatic metastatic tumors , hepatitis and hepatic contusion were analyzed retrospectively. The etiological mechanism of ILS was also discussed. Results On contrast - enhanced SCT scan, low - density line or annular line around the branches of hepatic vein , portal vein and/or intrahepatie inferior vena eava were found in all case , they presented as a kind of “halo sign” around the blood vessel. Conclusion The CT finding of ILS in hepatic diseases is quite characteristic and it is of great value in diagnosis of ILS.
