摘要
目的 探讨脑血吸虫病MRI表现与临床病理的关系 ,评价MRI诊断该病的应用价值。方法 手术病理或临床证实的 18例脑血吸虫病。采用 1.5TMRI扫描机 ,平扫及增强扫描。结果幕下 7例 ,幕上 11例 ;局灶性脑炎及脑膜炎型 5例 ,肉芽肿型 12例 ,脑萎缩型 1例。绝大部分病变T1WI为低、等信号 ,T2 WI为高信号 ,有结节状、斑点状或环状强化 ,并明显灶周水肿。结论 脑血吸虫病MRI表现有较高的特异性 。
Objective To study the relationship between MRI and histopathological findings of cerebral schistosomiasis,and the value of MRI on this disease. Methods 18 patients with cerebral schistosomiasis proved by pathological examination and laboratory test were enrolled in the study. Plain and Gd DTPA enhanced MRI were performed in all patients with GE 1.5 T MRI scanner. Results The lesions were located in infratentorial region in 7 cases and in supratentorial region in 11. There were three types of pathological pattern in the disease including focal encephalitis and meningiomas (5), granuloma (12), and encephalatrophy (1). Most of the lesions were iso or hypointensity on T 1WI, hyperintensity on T 2WI, with nodules, spot or ring like enhancement, and periphery edema. Conclusion MRI manifestations of cerebral schistosomiasis have specific features,which is a very important tool in early diagnosis and follows up for this disease.
