摘　　要：目的探讨脑血吸虫肉芽肿的cT特点。方法回顾分析9例脑血吸虫肉芽肿的CT与临床资料，其中4例经手术病理证实，另5例经实验室检查及吡喹酮试验治疗后临床确诊。所有病例均经平扫及增强。5例吡喹酮治疗后15—30d后复查CT。结果9例共11个病灶位于皮层及皮层下区，表现为单个或多个聚集的类圆形或不规则形结节，大小1．0—4．0cm。平扫为等或略高密度，增强后呈不均匀强化，周围有较宽的低密度带，且有占位效应。5例吡喹酮治疗后，病灶缩小或消失。结论脑血吸虫性肉芽肿有较典型的CT表现，结合临床、实验室检查及试验性治疗可确诊。Objective To study the CT findings of cerebral schistosomiasis granuloma （CSG）.Methods Nine patients with CSG,who comprised 4 cases confirmed by surgery and pathology and 5 cases confirmed by laboratory test and trial treatment with bitricide underwent CT scans of the brain without and with contrast enhancement.CT findings and clinical data of all patients were analyzed retrospectively.Five patients who received bitricide treatment were reexamined by CT at 15-30 days after the treatment.Results 11 lesions of 9 patients located in cortical areas or subcortical areas and appeared as solitary or coalescent round or irregular nodular shadows which ranged 1-4 cm in size.On CT images without contrast enhancement,the lesions of CSG were isodense or slight hyperdense.After administration of contrast medium,the lesions of CSG were non-homogeneous enhancement while their periphery had widish hypodense zone with space occupying effect.In 5 patients treated with bitricide CT scanning showed pathologic changes of the granuloma reduced or even disappeared during a fallow-up period of 15-30 days. Conclusion CSG has typical CT signs and its combination with laboratory test and trial treatment can make a correct diagnosis.
