【摘要】：目的:探讨婴幼儿颅内感染磁共振增强脑膜强化方式。方法:回顾性分析95例临床怀疑颅内感染患儿的临床资料和磁共振增强影像表现,其中男45例,女50例,年龄1天~2岁。95例患儿均行磁共振常规平扫及T1WI增强扫描,脑膜强化分为4级,确诊标准为脑脊液化验和临床诊断。结果:经临床确诊病毒性脑炎33例,脑膜强化分级0级14例,Ⅰ级0例,Ⅱ级12例,Ⅲ级7例。化脓性脑膜炎17例,0级0例,Ⅰ级15例,Ⅱ级0例,Ⅲ级2例。结核性脑膜炎25例,0级7例,Ⅰ级0例,Ⅱ级2例,Ⅲ级16例。临床排除感染20例。结论:婴幼儿软脑膜表面毛细血管丰富,因此仅凭软脑膜轻中度的强化,不能作为颅内感染的可靠征象,婴幼儿颅内感染早期病理改变轻微,影像表现也可以正常,需结合临床确诊。
[Abstract]:Objective: to explore the enhanced meningeal enhancement mode of MRI in infants with intracranial infection. Methods: the clinical data and MRI findings of 95 children with suspected intracranial infection were retrospectively analyzed, including 45 males and 50 females. All the 95 children, aged 1 day or 2 years, underwent conventional plain MRI and enhanced T 1WI. Meningeal enhancement was divided into 4 grades. The diagnostic criteria were cerebrospinal fluid assay and clinical diagnosis. Results: 33 cases of viral encephalitis were clinically diagnosed. Meningeal enhancement grade (14 cases), grade 鈪，
