脑囊虫病的磁共振成像特点

Magnetic resonance imaging for brain cysticercosis

目的探讨脑囊虫病的磁共振影像特点。方法对经临床及手术证实的26例脑囊虫病的磁共振资料进行回顾性分析。结果:脑实质型20例,混合型6例。26例中活动期2例,退变死亡期6例,钙化期4例,混合期14例。结论磁共振可清晰的显示脑囊虫数目、位置、大小等信息,对脑囊虫病的分型及分期有指导作用。结合CT检查和临床症状,有助于提高诊断率。

Objective To investigate the characteristics of cerebral cysticercosis by magnetic resonance imaging(MRI). Methods The MRI data of 26 cases of cerebral cysticercosis confirmed clinically and surgically was retrospectively analyzed. Results In the total 26 cases, 20 were brain parenchymal type and the other 6 were mixed type. By staging, 2 cases were at the active stage, 6 at the degenerating and dying stage, 4 at the calcification stage, and 14 at the mixed stage. Conclusion MRI is capable of demonstrating clearly the quantity, location and size of cerebral cysticercosis. And it facilitates the judgment on the typing and staging of cerebral cysticercosis. In combination to CT scan and clinical symptoms, MRI can increase the diagnostic rate of cerebral cysticercosis.
