脑血吸虫病11例的CT诊断报告

CT Analysis of Brain Schistosomiasis:Reports of 11Cases

目的:探讨脑血吸虫病的CT特征及其诊断价值。方法:11例行CT扫描,均结合患者疫水接触史、实验室检查证实。结果:14个病灶位于大脑半球,1个位于小脑半球。多发病灶4例,单发病灶7例。肉芽肿型6例,脑炎型4例,梗塞型1例。CT上呈低密度或等密度区,周围有水肿及占位效应,结节或斑片状强化,局部脑萎缩表现呈不规则低密度区,患侧脑沟增宽。结论:CT特征性表现结合血吸虫感染史有助于早期诊断,可为临床选择治疗方案提供依据。

Objective：To study CT features of brain schistosomiasis and its diagnostic value。 Materials and Methods：11 cases of brain schistosomiasis were scanned by CT,which diegnosied by laboratory test and the history of contacting the infected water.Results：All the lesions were located in cerebra.There were multi foci in hemisphere and single focus in cerebellar.They showed isodensity or a little low density,edema and mass of feets,nodular or patchy enhancement.The concomitant regional cerebral alrophy appeared irregular low density and enlarged ipsilateral sulci cerebri。 Conclusion：CT features together with the history of acute infection of schistosome are helpful to the early diagnosis of the disease and treat planning.
