Abstract：Objective To evaluate CT findings of traumatic cerebral infarction (TCI).Methods 54 cases of TCI were reviewed and analysed retrospectively.Results According to their differential clinical features and CT manifestations of TCI,which were classified as 2 types:typeⅠ,minor head injury and type Ⅱ,severe head injury,TypeⅠ(30 cases)occurred in children,especial in infants,cerebral lacunar infarctions in basal ganglia after a minor head injury were viewed in CT.In 23 cases (76.6%),spotty calcifications were found in the lendform nucleus.Type II(24 cases)occurred in adults or children after a severe head injury,cerebral infarctions of basal ganalia or and brain lobe, and useally complicated with intracranial hematomas,cerebral edema or contusion were viewed.Conclusions CT is very useful in the doagnosis of TCI. ......
