外伤性迟发性脑内血肿的CT表现及临床分析

目的探讨外伤性迟发性脑内血肿的CT及临床表现关系。方法回顾分析20例迟发性脑肿出现时间、CT及临床资料。结果20例迟发性脑内血肿在外伤后出现症状和体征,首次颅脑CT平扫均未见脑内血肿。伤后0.5h至数小时甚至几天才出现脑内血肿。其中30～60min者4例,1～3h者10例,3～24h者5例,24h以后者1例。首次扫描颅内可未见异常,可见硬膜外、硬膜下血肿或蛛网膜下腔出血,可在脑挫裂伤基础上发展形成。结论多次CT扫描可发现外伤性迟发性脑内血肿。

Approach on the relations between clinical manifestation and CT of traumatic tardive intracerebral hematoma

Objection] To approach the relations between clinical manifestation and CT of traumatic tardive intraeerebral hematoma. Method] Emergence time of 20 traumatic tardive intraeerebral hematoma eases were analyzed. Result] All the 20 eases of traumatic tardive intraeerebral hematoma had sings and symptoms after injuries and could not find intraeerebral hematoma in the first cranial computed tomography. Intraeerebral hematoma ap- peared in half an hour or several hours, even several days, Among these eases, 4 in 30~60 minutes, 30 in 1 ~3 hours, 5 in 3~24 hours, 1 in 24 hours. First cranial computed tomography had no abnormality or found epidural or subdural hematoma or subaraehnoid hemorrhage, which could also devolop in contusion and laceration of brain. Conclusions] Multi-CTsean could find traumatic tardive intraeerebral hematoma.
