等密度慢性硬膜下血肿的CT诊断价值

CT Features Analysis on Isodense Chronic Subdural Hematomas

目的:评价CT扫描对等密度慢性硬膜下血肿的诊断价值。方法:回顾性分析37例经手术证实为等密度慢性硬膜下血肿患者的CT表现。结果:37例患者所有病变均位于幕上,表现为颅板下弓形等密度影。单侧病变者32例,双侧病变者5例。中线结构不同程度向健侧或向血肿相对较小的一侧移位,脑沟、裂、池不同程度变浅或消失,侧脑室不同程度变窄、移位。结论:CT扫描能够比较准确的判断等密度慢性硬膜下血肿位置、大小、范围,对指导临床治疗有重要的价值。

Objective：To evaluate the value of CT scanning in the diagnosis of isodense chronic subdural hematoma.Methods：CT manifestation characteristics of 37 cases with isodense chronic subdural hematoma confirmed by surgery were retrospectively analyzed.Results：In 37 cases,all lesions were supratentorial,and arciformal with isodense under the skull.The unilateral lesions were 32 cases,and the bilateral lesions were 5 cases.The different degrees shift of midline structure to the contralateral or to the side with smaller hematoma were showed.The different levels shallowed or disappearance of cerebral sulcus,schizencephaly,cistern,and the different degrees shift and narrow of lateral ventricle were displayed.Conclusion：CT scans can accurately determine the location,size and scope of isodense chronic subdural hematoma,which is of great importance to guide the clinical treatment.
