Diffuse axonal injury is a relatively rare type of brain trauma when prolonged coma with generally poor clinical outcome is often associated with negative neuroimaging findings. Although magnetic resonance imaging is the method of choice for evaluation of diffuse axonal injury, computed tomography still plays an important role as an emergency visualization modality. We compared computed tomography findings with clinical data, short and medium-term outcomes and, if available, autopsy results of six consecutive patients admitted to our hospital during the year of 2009. We found that corpus callosum lesions were most closely associated with diffuse axonal injury, followed by subdural hematoma or hygroma.
弥漫性轴索损伤是一种相对罕见的脑外伤类型，长时间昏迷且临床预后通常较差，常与神经影像学检查结果阴性相关。尽管磁共振成像（MRI）是评估弥漫性轴索损伤的首选方法，但计算机断层扫描（CT）作为一种紧急可视化手段仍发挥着重要作用。我们将2009年我院连续收治的6例患者的CT检查结果与临床资料、短期和中期预后进行了比较，并在有条件的情况下与尸检结果进行了比较。我们发现胼胝体损伤与弥漫性轴索损伤关系最为密切，其次是硬膜下血肿或积液。
