目的:的:研究手足口病合并脑炎的MRI表现形式、病变部位、形态、信号特点,提高本病的MRI诊断水平。方法:2011年1月～7月底收治的手足口病重症病例中,12例有神经系统症状的患者,进行头颅MRI检查,使用HPILIPS1.5T Achieva Nova Dual。结果:12例中,病变位于延髓-脑桥交界处10例,延髓、中脑1例,延髓、右额叶1例。T1像上呈低信号12例,T2像上呈高信号12例,DWI像上呈高信号10例、呈低信号2例。病变周边模糊10例、边界清楚2例。结论:MRI诊断手足口病合并脑干脑炎具有重要的诊断价值。
Objective: To study the MRI manifestations of hand-foot-mouth disease combined with encephalitis, lesion location, morphology and signal characteristics and to improve the MRI diagnosis of this disease. METHODS: Of the HFMD severe cases admitted from January 2011 to the end of July 2011, 12 patients with neurological symptoms were examined by head MRI using the HPILIPS 1.5T Achieva Nova Dual. Results: In 12 cases, the lesions were located in the medulla - pontine junction in 10 cases, medulla oblongata, midbrain in 1 case, medulla oblongata, right frontal lobe in 1 case. T1 showed low signal in 12 cases, T2 showed high signal in 12 cases, DWI showed high signal in 10 cases, showed low signal in 2 cases. 10 cases of blurred peripheral lesions, border clear in 2 cases. Conclusion: MRI diagnosis of HFMD complicated with encephalitis has important diagnostic value.
