【摘要】：目的:探讨肝上皮样血管内皮瘤(EHE)的CT和MR表现。方法:回顾性分析8例经病理证实的肝脏EHE的CT和MRI表现及临床资料,总结其影像特征,8例均行CT检查,6例同时行MRI检查。由2位腹部放射诊断医生共同阅片分析影像学特点。结果:8例EHE病灶均为多发,紧邻肝包膜下生长,直径为3.0~150 mm。CT平扫表现为低密度;MRI平扫T1WI为低信号,T2WI为高信号。动态增强CT/MRI示≥3 cm的病灶增强后有向心性强化倾向,3 cm的病灶呈边缘环形强化,门脉期及延迟期持续环形强化。另外肝脏EHE还显示"包膜回缩征"(n=6)和"棒棒糖征",肝内静脉主干或分支终止于肿瘤的边缘(n=6)。结论:肝脏EHE在CT和MRI上表现具有一定特征性,尤其是紧邻肝包膜下生长,"棒棒糖征"、"包膜回缩征"及强化方式可为该病的鉴别诊断提供帮助。
[Abstract]:Objective: to investigate the CT and MR findings of hepatic epithelioid hemangioendothelioma (EHE). Methods: the CT and MRI findings and clinical data of 8 cases of pathologically proved liver EHE were analyzed retrospectively. The imaging features were summarized. All 8 cases were examined with CT and 6 cases with MRI. The imaging features were analyzed by two diagnostic abdominal radiologists. Results: all the 8 EHE lesions were multiple and grew next to the hepatic capsule. The low density was observed on plain scan with a diameter of 3. 0 ~ 150 mm.CT, while MRI showed low signal intensity in T1WI and high signal intensity in T2WI. Dynamic contrast-enhanced CT/MRI showed that the focus with 鈮，
