脑曼氏裂头蚴病MRI特点及追踪观察

MRI Characteristics and Track Observation of Cerebral Sparganosis

目的探讨脑曼氏裂头蚴病(cerebral sparganosis)的MRI影像学特点与价值。方法回顾性分析临床确诊的12例脑曼氏裂头蚴病MRI表现。结果 12例中单发5例,多发7例,共21个病灶,其中位于大脑半球16个、小脑3个、脑干2个;MRI显示病灶多呈条片状、斑片状异常信号影。T1WI为等低信号,T2WI为高信号,FLAIR为高信号,周围水肿明显但占位效应轻。增强后呈环状、串珠状、管状或逗点状强化,部分可见隧道征。随访复查9例,5个病灶出现游走,2例新出现隧道征。结论脑曼氏裂头蚴病的MRI表现具有特征性。

Objective To study the MRI imaging features of cerebral Sparganosis and value. Methods MRI imaging features of 12 patients with cerebral sparganosis confirmed by clinical were reviewed retrospectively. Results A total of 12 patients with a single in 5 cases, and multiple in 7 cases, for a total of 21 lesions, of which 16 were located in the hemisphere,3 in the cerebellum,2 in the brain stem. MRI showed lesions in cords twisted form, patchy anomalous signals shadows with moderate hypo -intensity on T~ WI and hyper- intensity on T2 WI and FLAIR. DWI showed hyper- intensity on the active period, and the surrounding edema was obvious but local mass effect was light. The enhanced MR imaging showed ericoid, beads - strings, tubular or comma, Soml lesions showed tunnel levy. Followed - up review in 9 cases, 5 lesions developed wander, 2 cases showed tunnel levy. Conclusion The MRI performance of cerebral sparganosis was characteristic.
