弥漫性轴索损伤的CT诊断

CT Diagnosis of Diffuse Axonal Injury

    摘要
  • 摘要: 目的: 进一步加深对弥漫性轴索损伤(DAI)临床及CT表现的认识,提高诊断水平。方法: 搜集32例DAI的临床及CT资料进行回顾性分析。结果: 32例DAI的CT表现为弥漫性脑肿胀32例,脑实质内出血灶23例,呈单发或多发,直径小于2cm,主要分布于皮髓质交界、胼胝体、基底节区和脑干,蛛网膜下腔出血15例,脑室内出血7例,合并硬膜下/外血肿8例,颅骨骨折7例。结论: DAI的临床与CT表现特点,对早期正确诊断具有重要意义。

     

    Abstract: Objective: To make a further recognizing of the manifestations of diffuse axonal injury (DAI) on clinic and CT images for improving diagnostic accuracy. Methods: The CT images data and its correlated clinic feature of 32 cases with DAI were analyzed retrospectively. Results: The diffuse brain edema were found in 32 cases. 23 cases had hemorrhage lesions (less than 2 cm in diameter) in brain parenchyma which were at corticomedullary junction, callosum, brain stem, basal gandlia, internal capsule. Subarachnoid hemorrhage 15 cases, intraventricular hemorrhage 7 cases, 8 cases were associated with epidural hematoma/subdural hematoma, and skull fracture 7 cases. Conclusion: CT manifestation and its correlated clinic feature of DAI can provide reliable evidence for the early accurate diagnosis of DAI.
