| 目的 探讨小儿肺炎支原体(mycoplasma pneumoniae,MP)脑炎的MRI表现特征,以指导治疗,判定预后。方法 对12例MP脑炎患儿进行头部MRI检查,并对其表现进行分析。结果 MRI异常9例,其中,白质内出现多发的、散在的点状或斑片状长T1长T2信号8例;两侧大脑半球弥漫性长T2信号2例;脑室扩大,侧脑室后角周围长T2信号2例;灰质(皮层)内脑回状长T2信号1例。结论 MP脑炎头部MRI异常表现为长T1长T2信号,能真实地显示MP脑炎脑实质受损情况,对临床治疗及预后判定提供了可靠的病理学基础。 |

| Objective To analyze the MR findings of pediatric mycoplasma pneumoniae (MP) encephalitis. Methods Twelve patients were performed MR scanning and the images were analyzed. Results MR showed abnormal findings in 9 cases, 8 of which showed multiple and scattered spot-like or patch-like lesions with long T1WI singnal and long T2WI signal in medulla, 2 of which showed diffuse high signal, 2 of which showed high signal near the posterior corn of lateral ventricles with cerebral ventricle enlargement, and 1 of which showed gyrus-like high signal in cortex. Conclusion The MR findings of MP encephalitis is long T1WI signal and long T2WI signal. MR examination is helpful to realize the injuried conditions in cerebellum and evaluate the prognosis. |
