少量外伤性蛛网膜下腔出血SCT诊断

目的提高对少量外伤性蛛网膜下腔出血的SCT诊断和鉴别诊断。方法回顾性分析经SCT复诊证实的105例少量外伤性蛛网膜下腔出血的SCT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SCT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。

Spiral CT Diagnosis of Small Amounts of Traumatic Suharachnoid Hemorrhage

Objective To improve spiral CT diagnosis and differential diagnosis of small amounts of traumatic subarachnoid hemorrhage(TSAH).Methods SCT features of 105 cases with small amounts of TSAH , which were demonstrated by SCT reexaminations , were retrospectively analyzed. Results The distributions of small amounts of TSAH included cerebral longitudinal fissure cistern in 47 cases, cerebral lateral fissure cistern in 30 cases , cerebral surface sulcus in 22 cases, tentorium of cerebellum in 6 cases. There were 12 cases of small amounts of TSAH with contusion and laceration of brain , Subdural hematoma or bone fracture of skull.Conclusions Spiral CT scan has important value in qualitation and level diagnosisa of small amounts of TSAH.
