目的:进一步分析颅脑外伤特殊CT征象,以提高诊断正确率。方法:回顾性分析了150例颅脑外伤的CT征象,其中骨折20例,颅内血肿68例(包括硬膜外血肿36例,硬膜下血肿23例,脑内血肿22例,复合血肿42例,迟发血肿7例),蛛网膜下腔出血26例,脑挫裂伤36例,外伤性气颅11例,外伤性脑梗塞10例,硬膜下积液16例。结果:颅脑外伤CT表现各有一定特征性,CT正确诊断率达100%,本组骨折20例,颅内血肿68例,蛛网膜下腔出血26例,脑挫裂伤36例,外伤性气颅11例,外伤性脑梗塞10例,硬膜下积液16例。根据外伤史治疗。结论:综合颅脑外伤的各种特殊CT征象,必要时辅以增强扫描有助于提高诊断正确率。
Objective: To further analyze the special CT signs of traumatic brain injury in order to improve the diagnostic accuracy. Methods: CT findings of 150 cases of craniocerebral trauma were retrospectively analyzed. There were 20 fractures and 68 cases of intracranial hematomas (including 36 cases of epidural hematoma, 23 cases of subdural hematoma, 22 cases of intracerebral hematoma, Cases, delayed hematoma in 7 cases), subarachnoid hemorrhage in 26 cases, brain contusion and laceration in 36 cases, traumatic craniofacial in 11 cases, traumatic cerebral infarction in 10 cases, subdural effusion in 16 cases. Results: CT manifestations of traumatic brain injury each have certain characteristic, the correct diagnosis rate of CT was 100%, the group of fractures in 20 cases, 68 cases of intracranial hematoma, 26 cases of subarachnoid hemorrhage, cerebral contusion and laceration in 36 cases, traumatic There were 11 cases of pneumothorax, 10 cases of traumatic cerebral infarction and 16 cases of subdural effusion. According to the history of trauma treatment. Conclusion: Combining all kinds of special CT signs of craniocerebral trauma, if necessary, supplemented with enhanced scan will help improve the diagnostic accuracy.
