摘要
目的 :探讨脑血吸虫病的MRI表现与临床联系 ,旨在提高对该病的临床、MRI特征的认识。方法 :搜集我院经MRI检查并经手术病理及临床证实的脑血吸虫病 14例。男性 9例 ,女性 5例 ,年龄 15～6 0岁 ,平均年龄 35岁。本组病例全部来自血吸虫疫区 ,均有疫水接触史 ,病程 7天～ 6个月不等。所有病例均采用GE1 0T超导磁共振机 ,每例均常规做MRI平扫及Gd DTPA增强扫描 ,其中 8例在行MRI检查前做过CT扫描。结果 :幕上 10例 ,幕下 4例 ;局灶性脑炎及脑膜炎型 4例 ,肉芽肿型 9例 ,脑萎缩型 1例。病变在T1WI为低、等信号 ,T2WI为高信号 ,其形态呈脑回状或指套状。Gd DTPA增强后 13例病灶出现不同程度强化 ,其中 6例呈结节状强化 ,6例呈多发、散在小点状强化 ,部分聚集呈簇状 ,1例幕上病变呈散在密集的结节状强化 ,同时伴有小点状 ,泥砂样强化。 1例病灶无强化 ,呈脑萎缩改变。所有病灶周围均有明显脑水肿表现 ,病灶大小与灶周水肿不成比例 ,即病灶体积小而水肿面积大 ,有不同程度占位征象。结论 :脑血吸虫病MRI表现有较高的特异性 ,对本病的诊断及鉴别诊断有重要价值。同时MRI检查也是术后随访及观察疗效的重要方法。
Objective: TO study the MRI of the cerebral schistosomiasis and to compare the finding with the clinical date. Material and Methods: 14 patients with pathological or clinical confirmed cerebral schistosomiasis underwent being diagnosed with a 1.0T MR unit(9 male and 5 femal,mean 35 years) were retrospectively analyzed. Among 8 cases underwent brain CT scanning. Results: Supratentarial lesions were found in 10 cases; infratentorial lesions 4 cases; local cerebritis type 4 cases; granuloma type 9 cases and cerebral atrophy type 1 case. plain MRI clearly revcaledthe lesions, which had lower-medium signal intensity on T1WI and high signal intensity on T2WI.There were 13 patients who underwent GD-DTPA contrast examination,6 cases revealed multiple nodulas enhancement.6 cases was multiple dotsenhancement,1 case without enhancement. Conclusion: MRI is of great value in diagnosing cerebral schistosomiasis and it's superior to other lmaging methods.
