目的提高对少量外伤性蛛网膜下腔出血的螺旋CT诊断和鉴别诊断。方法回顾性分析经螺旋CT复诊证实的105例少量外伤性蛛网膜下腔出血患者的螺旋CT表现。结果纵裂池出血47例,侧裂池出血30例,脑沟出血22例,小脑幕区出血6例。合并脑挫裂伤、硬膜下血肿或颅骨骨折共12例。结论螺旋CT扫描对少量外伤性蛛网膜下腔出血的定性、定位诊断有重要价值。
Objective To improve the diagnosis and differential diagnosis of a small amount of traumatic subarachnoid hemorrhage by spiral CT. Methods Retrospective analysis of spiral CT findings confirmed by spiral CT in 105 cases of traumatic subarachnoid hemorrhage in patients with spiral CT findings. Results Longitudinal fissure pool hemorrhage in 47 cases, 30 cases of lateral fissure hemorrhage, sulci hemorrhage in 22 cases, 6 cases of cerebellar bleeding. Combined cerebral contusion, subdural hematoma or skull fracture in 12 cases. Conclusion Spiral CT scan is valuable for the qualitative diagnosis and localization of traumatic subarachnoid hemorrhage.
