外伤性腔隙性脑梗塞的CT诊断

CT Diagnosis of Traumatic Cerebral Lacunar Infarction

目的 :探讨CT在外伤性腔隙性脑梗塞诊断中的价值及其特征。材料与方法 对 3 6例头颈外伤后 ,临床上主要表现为不同程度的偏瘫患者均行横断位CT扫描。结果 外伤性腔隙性脑梗塞好发于基底节 内囊区 ,均位于豆状核、尾状核及内囊区 ,呈小片腔隙性低密度影。结论 CT扫描检查对外伤性脑梗塞的准确诊断、估计病变程度、预后及法医学鉴定有肯定价值。

Objective To evaluate CT findings of traumatic cerebral lacunar infarction in diagnosis.Materials and Methods Axial CT scanning was performed in 36 cases with traumatic cerebral infarction and clinically manifesting different degrees of hemiplegia.Results The infarctions appeared as small lacunar lesions, and were located mainly in the regions of lenticular nucleus, caudate nucleus and internal capsule.Conclusion CT can accurately demonstrate the site, extent and size of the lesion, postulate the prognosis, and, therefore, is very valuable for medicolegal expertise.
