外伤性少见部位硬膜下血肿（附35例CT分析）

目的提高对大脑镰、小脑幕硬膜下血肿的CT诊断及鉴别诊断水平。方法回顾性分析35例资料完整的外伤性大脑镰、小脑幕硬膜下血肿的CT征象。结果35例中,34例发生于单侧,双侧1例。大脑镰硬膜下血肿5例表现为细绳索状,7例呈粗绳索状;小脑幕硬膜下血肿4例呈片状,8例呈新月形,3例呈扇形;小脑幕并有大脑镰硬膜下血肿6例呈镰刀形,2例呈“Y”形。结论大脑镰、小脑幕硬膜下血肿是硬膜下血肿的一种少见类型。只要全面分析病变CT征象,一般都能作出正确诊断。

The Traumatic SubduralHematoma at Non-typical Location:CT analysis of 35 cases

Objective:To improve the CT diagnosis and differentiated diagnosis of subdural hamatomas at cerebral flax and cerebellar tentorium.Methods:The CT signs of 35 cases with subdural hematomas at cerebral flax and cerebellar tentorium were analyzed tetrospectively.Results:Of 35 cases,34 cases were unilateral,1 case was bilateral,5 cases of cerebral flax subdural hematomas presented as thin funiform,7 cases presented as thick funiform.4 cases of cerebellar tentorium hematomas presented as flakes,8 cases presented as crescent-shaped,3 cases presented as sectors.In 8 cases of subdural hamatomas of cerebral flax with cerebellar tentorium,6 cases presented as falciform,2 cases presented as"Y" shape.All of 35 cases were hyperdence,17 cases had no signs of space-occupying,18 cases had a little degree of space-occupying signs.Conclusion:Subdural hematomas of cerebral flax and cerebellar tentorium are little probability incident but if we analyzed the CT signs carefully,the correct diagnosis will be made.
