脑弥漫性轴索损伤的CT表现（附68例分析）

目的：分析脑弥漫性轴索损伤（DAI）的CT征象，为DAI的诊断提供影像学依据。方法：回顾性分析68例经临床确诊的DAI的早期CT表现。其中，男52例，女16例，年龄6-72岁，平均32.3岁，51例采用保守治疗，17例行开颅减压术，死亡37例（54.4%)，重残21例（30.9%)，CT扫描在伤后30分钟至24小时进行，使用岛津SCT-4500TE型全身CT机行非增强扫描。结果：脑白质内单发或多发小出血灶49例（大脑半球37例，基底节区4例，胼胝体6例，脑干2例），蛛网膜下腔出血17例，脑室出血5例，弥漫性脑肿胀58例。结论：CT是早期诊断DAI的有效方法。并可提示病人的预后。

CT manifestation of diffuse axonal iajury(analysis of 68 cases)

Objective:To provide reliable evidence for clinical diagnosis of diffuse axonal injury(DAI)based on study the CT signs in DAI. Methods:CT signs of 68 cases of DAI confirmed clinically were reviewed. The patients including 16 female and 52male, 6～72 years old. 51 patients were treated in medical way, and 17 operated craniotomy, 37 patients(54.4 96 )died, 21 patients (30.9%)have become poor outcome. All the patients were examined with plain CT scan in range from 30 minutes to 24 hours after injury. Results:CT scans of 68 cases with DAI of early phase showed one or more small hemorrhagic lesions at white matter 49 cases(including cerebral hemisphare 37 cases,based node 4,copus collosum 6,brain stem 2),SAH 17,interventricular hemorrhage 5, and brain swelling 58 cases. Conclusion: CT scan is a useful techniques for early diagnosis of DAI, and can provide useful information about the patients prognosis.
