Abstract
Computerized tomography (CT) scans of 72 patients with severe head injury were reviewed and the findings were compared with the prognosis. In this study, CT scan was performed within 24 hours after the accident in all cases. Approximately half of the patients showed poor prognosis.
Findings on CT were classified into 5 types: cerebral contusion (type 1), intracranial hematoma (type 2), cerebral contusion with intracranial hematoma (type 3), subarachnoid hemorrhage (type 4), and posterior fossa hematoma (type 5). In the present study 70% of patients had type 1 or type 2. The prognosis of both type 1 and type 3 was poor.
Findings on ambient and guadrigeminal cistern (AQC) have a close correlation with the outcomes. The patients, whose AQC disappeared, showed the worst outcomes. However, the patients with type 5 showed good outcomes inspite of disappeared AQC.
