title: Evaluation of head trauma by computed tomography.
abstract: A wide spectrum of traumatic abnormalities has been demonstrated by computed tomography. CT findings in acute trauma range from cerebral edema and contusion to intracerebral or extracerebral hematoma, subarachnoid and intraventricular hemorrhage and varying combinations thereof. Late traumatic changes shown by CT include chronic subdural hygroma, post-traumatic infarct, and porencephaly and hydrocephalus. The latter findings are indistinguishable from changes resulting from degenerative or ischemic brain disease. Follow-up CT scanning elucidates the natural course of various traumatic lesions. Occasionally, it may uncover occult, delayed sequelae which can be remedied surgically before irreparable brain damage occurs.
