目的 探讨脑型血吸虫病的临床特点及诊断方法.方法 回顾性分析42例脑型血吸虫病的CT、 MRI及脑脊液(CSF)免疫学检查资料.结果 通过影像学及免疫学检查确诊40例,1例不能完全排除脑肿瘤通过术后病理检查确诊,1例高度怀疑脑型血吸虫病经吡喹酮诊断治疗证实.结论 CT及MRI对脑型血吸虫病的定位和定性诊断有很大价值.MRI在显示主要病理改变时,其敏感性和准确性均较CT高.CSF免疫学检查对脑型血吸虫病鉴别诊断有重要价值.“,”Objective To explore the clinical characteristics and diagnostic methods of cerebral schistosomiasis.Methods The data of CT,MRI and the cerebral spine fluid(CSF) immunoassay in 42 patients with cerebral schistosomiasis were analyzed retrospectively.Results Forty cerebral schistosomiasis patients were diagnosed by the iconography and immunoassay,1 by the postoperative pathological examination and 1 by diagnostic treatment with praziquantel.Conclusions CT and MRI are of great value to determination of the position and nature of the cerebral schistosomiasis.The sensitivity and accuracy of MRI are better for indicating the main pathological changes of the disease than those of CT.The CSF immunoassay plays an important role in the differential diagnosis of cerebral schistosomiasis.
