脑裂头蚴病的MRI表现及相关病理改变

目的 分析脑裂头蚴病的MRI表现及MRI对该病的诊断价值. 方法 回顾性分析8例经手术病理证实的脑裂头蚴病的MRI表现. 结果 8例脑裂头蚴病的MRI表现在T_1WI上为低信号、T_2WI上为高信号,病灶周围可见大片水肿信号影.增强后大部分病灶呈类似虫体形态的环状、结节状、串珠状及扭曲的线条样强化影.其中3例多次MRI复查,病灶的位置及形态有改变.结论 脑裂头蚴病的病理表现具有一定的特征性,MRI对此病的诊断和鉴别诊断有重要的临床意义.

Cerebral Sparganosis:MR Imaging Features and Pathology

Objective To analyze MRI manifestations of cerebral sparganosis and the diagnostic value of MRI.Methods MRI findings in 8 patients with proven cerebral sparganosis by pathological examination were reviewed.Results The lesions were hypointense on T1WI and hyperintense on T2WI with edema of brain around the lesions.Most of the lesions were markedly enhanced with ring-type,nodules,tortous beaded shape or tortuous linear like worm past-enhanced scans.The location and shape of the lesions in 3 cases were changed on followed-up MRI.Conclusion There are some specific pathological findings in cerebral sparganosis.MRI is of important clinical value in diagnosis and differential diagnosis of cerebral sparganosis.
