【摘要】：目的探讨磁共振脑膜强化模式在婴幼儿颅内感染诊断中的应用价值,为临床诊治提供参考依据。方法选取2013年7月-2014年6月医院收治的76例经脑脊液检查确诊的颅内感染婴幼儿,所有患儿均经T1WI增强扫描以及磁共振常规平扫,脑膜强化共有4级,观察分析所有婴幼儿磁共振脑膜强化的影像学表现。结果磁共振检查中,12例(15.79%)化脓性脑膜炎有10例(83.33%)表现为全脑膜强化;28例(36.84%)例病毒性脑膜炎中有8例(28.57%)表现为软脑膜可疑过度强化,9例(32.14%)表现为蛛网膜-软脑膜强化,5例(17.86%)表现为全脑膜强化级;21例(27.63%)结核性脑膜炎有13例(61.90%)表现为脑基底池异常强化;15例(19.74%)其他感染中4例(26.67%)表现为脑基底池异常强化,1例(6.67%)表现为软脑膜可疑过度强化,2例(13.33%)表现为蛛网膜-软脑膜强化;增强后12例化脓性脑膜炎,10例(83.33%)为Ⅰ级,2例(16.67%)为Ⅲ级;28例病毒性脑膜炎中14例(50.00%)为0级,9例(32.14%)Ⅱ级,5例(17.86%)Ⅲ级;21例结核性脑膜炎中7例(33.33%)为0级,1例(4.76%)Ⅱ级,13例(61.90%)Ⅲ级;15例其他感染中8例(53.33%)0级,1例(6.67%)Ⅰ级,6例(40.00%)为Ⅱ级。结论婴幼儿具有较为丰富的软脑膜表面毛细血管,仅仅依靠软脑膜轻中度强化,难以作为颅内感染的可靠征象,再加之婴幼儿颅内感染早期病理变化较为轻微,因此在确诊中需要和临床诊断相互结合。
[Abstract]:Objective to evaluate the value of magnetic resonance meningeal enhancement model in the diagnosis of infantile intracranial infection. Methods from July 2013 to June 2014, 76 infants with intracranial infection diagnosed by cerebrospinal fluid examination were selected. All of them underwent T1WI enhanced scanning and conventional plain MRI. Meningeal enhancement has four levels. Results in Mr examination, 12 cases (15.79%) and 10 cases of suppurative meningitis (83.33%) showed total meningeal enhancement in 28 cases (36.84 cases) and viral meningitis in 8 cases (28.57%). Suspected excessive enhancement of pia meninges 9 cases (32.14): arachnoid / pial meningeal enhancement (5 cases / 17.86): total meningeal enhancement grade (21 cases)) tuberculous meningitis (13 cases (61.90)): abnormal enhancement of basal cistern (15 cases) and other infections (4 cases). The abnormal enhancement of basal cistern was found in 1 case (6. 67) and suspected excessive enhancement of pia meninges in 2 cases (13. 33%) and arachnoid-pial meningeal enhancement in 2 cases. 12 cases of suppurative meningitis (n = 10) with suppurative meningitis (n = 10) with grade 鈪，
