摘　　要：回顾性分析 37例等密度硬膜下血肿 (ISDH)的 CT表现及形成机制。间接征象的观察在 ISDH诊断中占有重要地位 ,主要有 :1侧脑室受压变形及中线结构移位 ,2脑灰白质界面广泛一致性内移 ,3脑白质凹陷征 ,4脑沟消失及脑回聚拢内移征。 CT增强扫描对 ISDH的诊断有很大帮助 ,表现为 :1患侧脑表面血管内移 ,2血肿膜呈点线状高密度影 ,3血肿腔本身增强。认为熟悉 ISDH各种 CT征象 ,增强扫描征象 ,必要时辅以冠位增强扫描能提高We retrospectively studied the CT manifestation and formation mechanism of 37 isodense chronic subdural hematoma(ISDH)cases It has a high station in diagnosis of ISDH to observe the indirect manifestation Major points are①Lateral ventricle is out of shape and the midline structure moves inside for compression ②The interface of gray matter with white matter moves inside widely and concordance ③The depressed sign of brain white matter ④The disappearing of brain sulcus and the gathering with ingression of brain whiter matter The enhanced scan of CT is very helpful in diagnosis ISDH These shows include①The blood vessels on brain surface at the disease side move inside ②The hematoma membrane shows high density image as point to line ③The hematoma is in high density We think that it can improve the diagnosis rate of ISDH if we are familiar with all kinds of CT manifestation,CT enhanced scan signs and coronary enhanced scan
