摘　　要：目的探讨多发结节型脑血吸虫病的MRI表现特征。方法45例经手术病理或临床证实的多发结节型脑血吸虫病患者，常规行MRI平扫及增强扫描。对病变的部位、数目、信号改变、灶周水肿等几个方面进行回顾性分析。结果多发结节型脑血吸虫病45例，增强扫描均呈多发大小不等均匀结节状强化。所有病例均可见结节融合和“局限分布”征象。多处病灶者16例，均可见“主体病灶”。结论多发结节的融合和“局限分布”征象、多处病灶的“主体病灶”表现是多发结节型脑血吸虫病的特征性MRI表现。Objective To evaluate MRI characteristics multi-nodular cerebral schistosomiasis. Methods Conventional and en- hanced MRI were performed on 45 patients with multi-nodular cerebral schistosomiasis confirmed by surgical pathology or clinic. The locations, numbers, signal of the lesions and the perifocal edema were analyzed retrospectively. Results There were multiple nodular pattern appeared in 45 cases. Multiple enhancing punctate nodules were documented in all cases. Nodules showed fusion and limited distribution signs in all cases. 16 patients had multiple lesions, in which ＂the main lesion＂ were seen. Conclusion Fusion and limited distribution signs of multiple nodular and ＂the main lesion＂ are the characteristics manifestations of multi-nodular cerebral schistosomiasis on MRI.
