为了解不同病期结核性脑膜炎 (TM)患儿的头颅CT、MRI改变及与临床的关系 ,对91例不同病期TM患儿的头颅CT、MRI及临床进行分析。结果头颅CT检查67例 ,异常58例 ,异常率为86.6 % ;头颅MRI检查38例 ,异常35例 ,异常率为92.1 %。CT改变特点与MRI基本一致 ,早期仅为脑池改变或轻度脑实质低密度影 ;中期则发展为脑水肿、脑积水 ;晚期可见脑实质低密度、混杂高密度影及脑池受压、闭塞、粘连等。临床疗效良好者影像学改变轻 ,疗效差者影像学改变重。提示CT、MRI检查 ,尤其MRI对TM的诊断、病期和预后判定有重要意义。
To understand craniocerebral CT and MRI changes in children with tuberculous meningitis (TM) at different stages and their relationship with clinic, craniocerebral CT, MRI and clinical data of 91 children with different stages of TM were analyzed. Results There were 67 cases of craniocerebral CT examination and 58 cases of abnormality. The abnormal rate was 86.6%. There were 38 cases of cranial MRI examination and 35 cases of abnormality. The abnormal rate was 92.1%. CT changes the characteristics of the same with MRI, early only changes in the cerebral cortex or mild brain parenchyma low density; mid-term development of cerebral edema, hydrocephalus; late visible parenchyma low density, mixed high density and cisternal compression , Occlusion, adhesions and so on. Good clinical efficacy of imaging changes in light, poor efficacy of imaging changes in weight. Tip CT, MRI examination, especially MRI diagnosis of TM, stage and prognosis of great significance.
