摘　　要：目的探讨慢性硬膜下血肿不同时期病理变化与CT表现。方法回顾性分析经螺旋CT诊断的慢性硬膜下血肿113例。结果113例125个血肿。血肿形态表现为弓背形、新月形94个(占75.2%),梭形和双凸形25个(占20.0%),不规则形6个(占4.8%);血肿密度表现为混杂密度66个(占52.8%),等密度29个(占23.2%),低密度30个(占24.0%);并中线结构移位占81%,侧脑室受压变形占67%,脑回皱襞聚拢内移占89%,脑灰白质内移占78%。结论慢性硬膜下血肿螺旋CT与病理对照分析对提高CT诊断和指导临床治疗有重要作用。Objective To investigate pathological change and CT appearance characteristic of chronic subdural hematoma（SDH） in different period. Methods Retrospectively analyze ll3 cases of chronic subdural hematoma which were diagnosed by helico-CT. Results 125 haematomas were seen in 113 cases. The appearances of the haematomas are arcus antiform and crescentiform（94, 75.2% of the them）, fusiform shape and dipl-convex shape（25, 20.0% of the them）, irregular shape （6, 4.8% of the them ）. Densities of hematoma involved mixed densities（66, 52.8% of them）, isodensities（29, 23.2% of them）, low densities（30, 24% of them）. Mid-line shift（81%）, lateral cerebral ventricle allaxis due to be compressed（67%）, plica of cerebral convolution gather together and ingression（89%） and grey matter of brain ingression（78%） were seen in the cases. Conclusion Coss-check analysis of CT and pathology in chronic subdural hematoma plays an important role in increasing CT diagnosis and guiding clinical therapy.
