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.

摘要

计算机断层扫描已显示出各种各样的创伤性异常。急性创伤的CT表现范围从脑水肿和脑挫伤至脑内或脑外血肿、蛛网膜下腔和脑室内出血以及它们的不同组合。CT显示的晚期创伤性改变包括慢性硬膜下积液、创伤后梗死、脑穿通畸形和脑积水。后述表现与退行性或缺血性脑疾病所致改变无法区分。随访CT扫描可阐明各种创伤性病变的自然病程。偶尔，它可能发现隐匿的、延迟出现的后遗症，这些后遗症可在发生不可修复的脑损伤之前通过手术得到补救。
