摘　　要：目的：探讨外伤性迟发脑内血肿可能的首次检查的CT表现的特点及应该复查的时间。方法：收集40例颅脑外伤迟发性脑内血肿患者，对其CT影像特点进行分析，并随机抽取无迟发性脑内血肿患者进行对照。结果：迟发性脑内血肿的出现时间为24h之后，主要表现包括：局限性脑实质密度减低，灰白质分界不清；局限性脑轻度占位效应、硬膜下血肿。结论：外伤后首次CT检查，当出现局限性脑实质密度减低，灰白质分界不清；局限性蛛网膜下腔出血；局限性脑轻度占位效应、硬膜下出血的患者，应在24-48h内进行CT复查。Objective To study the first CT characteristics of traumatic delayed intracerebral hematoma and the re - check time. Method For 40 cases with traumatic delayed intracerebral hematoma were collected, and their CT manifestation were analyzed. Another 50 cases of head trauma without delayed intracerebral hematomas were included randomly as control. Results The traumatic delayed intracerebral hematomas presented 24 hours later after injnred. The abnormal findings of CT studies of 40 delayed intraeerebral hematomas included ： Decreased density of local brain parenchyma and dissappered difference between gray and white matter of the same area, local subarachnoid space hemorrhage, slight mass effect of local brain parenehyma, and subdural homatoma of local brain parenchyma. Conclusion The decreased density of local brain parenchyma, the dissappercd difference between gray and white matter of the same area, local subarachnoid space hemorrhage, and local swollen of brain present in the initial CT study of the patients with head trauma should he taken as indicators of delayed hemorrahage of the same area of brain and it is necessary to do follow up CT studies to exclude it.
