等密度硬膜下血肿的CT诊断

CT diagnosis of the isodense subdural hematoma

目的回顾性分析等密度硬膜下血肿的CT表现,提高对本病的诊断水平。方法收集经手术证实的等密度硬膜下血肿35例,分析其CT表现。结果主要CT征象包括:血肿等密度、脑室变形、脑沟消失、灰白质界面内移。结论脑室、脑池及脑沟的变形移位及灰白质界面内移是诊断等密度硬膜下血肿的重要CT征象。

Objective To retrospectively analyzed the isodense subdural hematoma appearances of CT,so as to improve the diagnosis accuracy of the disease.Methods Thirty-five cases of the isodense subdural hematoma confirmed by operation were collected.Results The CT important signs included:isodense subdural hematoma,cerebral ventricle deformity,disappearance of the cortical sulci,and gray-white matter interface(G-WMI)displacement.Conclusion Cerebral ventricle deformity,disappearance of the cortical sulci、gray-white matter interface(G-WMI)ingression are the important CT sign for us to diagnosis the isodense subdural hematoma
