摘　　要：目的探讨小儿手足口病(hand-foot-mouth disease,HFMD)合并脑干脑炎、脊髓炎MRI表现特征,以提高对本病的认识。资料与方法回顾性分析7例有阳性影像学表现的小儿HFMD合并脑干脑炎、脊髓炎患者的MRI特征性表现。结果 4例病灶以桥脑、延脑交界部为主,1例位于桥脑,呈略长T1、长T2斑片状信号。2例病灶在横断位上表现为对称性小斑片状信号。2例病灶均位于脊髓圆锥,呈长条形略长T1、长T2信号,病灶在横断位上表现为对称性小斑片状信号。结论 HFMD合并脑干脑炎、脊髓炎MRI表现有一定特征性。MRI能真实地显示HFMD脑干脑炎、脊髓炎脑部、脊髓受损情况,可对临床治疗提供可靠的影像学依据。Objective To explore MRI characters of hand-foot-mouth disease （HFMD） brainstem encephalitis and myelitis,so as to increase diagnostic level. Materials and Methods 7 children’s HFMD of brain stem encephalitis and myelitis with positive imaging appearances were analyzed. Results The lesions of brainstem lied at the boundary of medulla oblongata and pons in 4 cases,pons in 1 case. They all appeared long T1,long T2 speckle signals. 2 of which showed symmetrical small patch shape lesions on axial T2WI and T1WI. The lesions of spinal cord lied at spinal cord taper in 2 cases,it showed symmetrical small patch shape lesions on axial T2WI and T1WI. Conclusion MR images can reflect the damage of brainstem and spine in HFMD with brainstem encephalitis and myelitis. It can provide reliable radiology information for physicians.
