目的探讨肝脓肿壁的增强CT表现及其在鉴别诊断中的价值.方法选择近两年间行增强CT检查诊断为、疑似或不能除外肝脓肿的病例31例,经穿刺病理证实为肝脓肿18例,原发性肝癌6例,胆管细胞癌4例,转移瘤3例,进行回顾性分析,重点观察肝脓肿壁的强化特点并归纳鉴别点.结果18例肝脓肿均可见“勾线征”,脓肿壁呈均匀细线样强化,不伴乳头,总体表现为单环5例,大小环簇集11例,蜂窝状2例,13例肝肿瘤无1例出现该征.结论勾线征是肝脓肿壁的增强CT特征,有助于肝脓肿的诊断和鉴别诊断.

Objective To investigate enhanced CT features of hepatic abscess wall and its role in differentiation of hepatic tumor.Methods The CT imaging data of 31 hepatic abscesses diagnosed or suggested with enhanced CT in recent two years,including 18 hepatic abscesses,6 primary hepatic carcinomas,4 bile duct carcinomas,3 hepatic metastatic tumors,proved by the pathology of biopsy,were retrospectively analyzed,focusing on contrast-enhanced CT features of hepatic abscess wall.Results A phenomenon of uniformly thin line enhancement of abscess wall and no mastoid enhancement superimposed on,known as the linear definition sign,was seen in all 18 hepatic abscesses,showing in whole single ring(n=5),or concomitant big and small rings(n=11),or honeycomb(n=2),but not in all 13 hepatic tumor.Conclusion The linear definition sign is characteristic and very helpful for the diagnosis of hepatic abscess and the differential diagnosis from hepatic tumor.
