儿童手足口病合并中枢神经系统感染的MRI表现(附36例分析)

MRI findings of 36 cases with neurologic complications in childrens with hand-food and mouth disease

目的探讨手足口病患儿合并中枢神经系统感染的MRI表现。方法回顾性分析本院36例手足口病患儿合并中枢神经系统感染的MRI表现特点。结果 MRI表现为脑干偏背侧片状等或稍长T1长T2信号7例,其中中脑受累2例,桥延交界区受累5例。MRI表现为脊髓前角等长T1长T2信号29例,其中颈段脊髓受累7例,上胸段受累1例,下胸段至腰骶段脊髓受累19例,累及多段脊髓3例;脊髓内双侧受累25例,单侧受累4例。结论 MRI能清晰显示手足口病患儿合并中枢神经系统感染的病变特点,是影像学首选检查方法,为临床诊断治疗、评价治疗效果提供了可靠依据。

Objective To study the MRI manifestations of infection in children with hand foot and mouth disease complicated with central nervous system. Methods A retrospective analysis of MRI manifestations of 36 cases of children with hand foot mouth disease complicated with central nervous system infection was performed. Results MRI showed partial dorsal brainstem sliced or slightly long T1 and long T2 signal in 7 cases, including 2 cases of cerebral involvement, 5 cases of pontomedullary junction involvement. MRI manifestations of spinal cord anterior horn length T1 and long T2 signal were found in 29 cases, including 7 cases of cervical spinal cord involvement, lcase of upper thoracic segment involvement, 19 cases of lower thoracic and lumbosacra] spinal cord involvement, 3 cases involving multiple segments of the spinal cord; 25 cases of spinal cord bilateral involvement and 4 patients with unilateral involvement. Conclusion MRI can clearly show the lesion characteristics of infection in children with hand foot and mouth disease complicated with central nervous system, which is the preferred method of imaging examination, and can provide reliable basis for clinical diagnosis, treatment, and therapeutic effect evaluation.
