CT Feature of Delayed Contra Coup Celebral Injury

Objective: To intensify the cognition of delayed contra coup cerebral injury. Methods: CT images of 26 cases with newly appeared lesions and/or enlarged lesions in the opposite areas were retrospectively analyzed. Results: On the CT scans at the first time, 10 cases showed cerebral contusion and/or laceration, 13 cases did subarachnoid hemorrhage(SAH), 7cases did subdural hematoma(SDH), and 4 cases did epidural hematoma(EDH). On CT re-examination scans, 18 cases showed intracranial hematoma, 8 cases did cerebral contusion and/or laceration, and 6 cases did EDH. Conclusion: Delayed contra coup cerebral injury presents a variety of CT images. It's necessary to take CT re-examination, particularly for the patients with cerebral contusion and/or Laceration and for the patients with SAH on first CT scan. The optimal time for CT re-examination is in three days after trauma.
