目的描述脑部日本血吸虫病的MRI特征性表现。方法回顾性分析2000年至2005年上海和江苏两地21例经临床明确诊断为脑部血吸虫病患者的临床资料和MRI表现。结果 MRI初步显示,13例表现为单一病灶,8例表现为多数病灶,注射对比剂后,所有感染区域表现为大量的呈簇状聚集的强化结节,10例可见明显的线状强化。结论脑部感染日本血吸虫病的特征性表现是,感染区域表现为大量的呈簇状聚集的强化结节,有时可见明显的线状强化。在血吸虫流行地区,这种典型表现对该病的诊断是有用的,在非流行区域对患者的诊断也是有帮助的。
Objective To describe the MRI features of schistosomiasis japonica in the brain. Methods The clinical data and MRI findings of 21 cases of schistosomiasis patients diagnosed clinically from 2000 to 2005 in Shanghai and Jiangsu Province were retrospectively analyzed. Results MRI initially showed that 13 cases showed a single lesion and 8 cases showed most lesions. After injection of contrast agent, all the infected areas showed a large number of enhanced nodules clustered, and 10 cases showed obvious linear enhancement. Conclusions The characteristic manifestation of schistosomiasis japonica infection in the brain is that the infected area is characterized by a large number of enhanced nodules clustered in clusters and sometimes with obvious linear enhancement. In schistosomiasis endemic areas, this typical manifestation is useful for the diagnosis of the disease, and it is also helpful in the diagnosis of patients in non-endemic areas.
