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.
