颅内炎性肉芽肿287例CT表现及鉴别诊断

CT diagnosis and antidiastole of intracranial inflammatory granuloma:An analysis of 287 cases

目的探讨颅内炎性肉芽肿的CT表现及病理基础。方法回顾分析287例颅内肉芽肿的CT动态表现、临床资料及实验室检查资料。结果结核性肉芽肿132例(45.99%),小脓肿112例(39.02%),病毒性脑部炎症10例(3.48%),霉菌性肉芽肿11例(3.83%),囊虫性肉芽肿22例(7.67%);CT平扫均表现为低密度,增强表现不同。结论尽管颅内炎性肉芽肿有一些共性CT表现,但不同致病因子在不同病理阶段有不同的CT表现,结合其他相关资料可作为颅内炎性肉芽肿鉴别诊断及疗效评价的主要方法。

Objective To summarize pathological and CT diagnosis of intracranial inflammatory granuloma.Methods The data of 287 cases of intracranial inflammatory granuloma patients were analyzed.Results Some 132 cases with tuberculosis granuloma,accounted for 45.99%;112 cases with microabscess,accounted for 39.02%;10 cases with viral brain inflammation,accounted for 3.48%;11 cases with mould granuloma,accounted for 3.83%;22 cases with cysticercosis granuloma,accounted for 7.67%.All lesions showed low density by CT scan and enhancement showed difference.Conclusion Intracranial inflammatory granuloma has some common CT manifestations.Different pathogenic factors in different pathological stages have some different CT manifestations.Combined with other related material can be the main effective assessment method.
