[CT brain scanning in the diagnosis and localisation of cerebral schistosomiasis].

CT scanning was performed on 25 cases of cerebral schistosomiasis. The images of the granuloma caused by schistosome eggs showed a high density mass shadow while the edema of the white matter showed a low density shadow. Combining CT scanning, with case history, clinical signs and immunologic assay we could make a correct diagnosis for each of the patients about the pathologic site and nature. The correlations between the images of CT scanning and clinical pathology were analysed and a better treatment regimen was discussed based on our experience. Some of the patients treated with praziquantel and checked by CT scanning showed pathologic changes of the granuloma disappeared during a follow-up period of 3-12 months.
