[Analysis of 112 cases with diffuse axonal injury].

OBJECTIVE

To investigate the relationship between the diffuse axonal injury (DAI) and cerebral contusion, primary brain stem injury and brain concussion.

METHODS

One hundred and twelve cases with DAI were analyzed according to the characteristics of clinical signs and imaging features.

RESULTS

Of 112 cases of DAI, 70.5% injured in traffic accident, 60.7% injured with blunt trauma more than one time and 71.4% injured with cerebral contusion. And 90 cases with brain with hemorrhage were found in CT or MRI imaging.

CONCLUSION

DAI may be associated with cortical contusion and primary brain stem injury. The CT or MRI is useful to investigate the cause of death and to evaluate the personal disability.
