迟发性颅内对冲伤26例CT分析

CT Feature of Delayed Contra Coup Celebral Injury

目的 :提高对迟发性颅内对冲伤的认识。方法 :迟发性颅内对冲部位新病变和 (或 )病变增大者 2 6例 ,分析其CT表现。结果 :首次CT检查发现 :脑挫裂伤 10例、蛛网膜下腔出血 (SAH) 13例、硬膜下血肿 (SDH) 7例、硬膜外血肿 (EDH) 4例 :复查发现 :脑内血肿 18例 (其中 8例为原挫裂伤部位出现血肿 )、脑挫裂伤 8例、EDH6例。结论 :脑对冲伤后可出现多种情况的迟发性对冲性颅内损伤 ,其发生率较高 ,应注意复查CT ,尤其是首次检查出现脑挫裂伤或SAH者 ,更是复查对象。伤后

Objective: To intensify the cognition of delayed contra coup cerebral injury. Methods: CT images of 26 cases with newly appeared lesions and/or enlarged lesions in the opposite areas were retrospectively analyzed. Results: On the CT scans at the first time, 10 cases showed cerebral contusion and/or laceration, 13 cases did subarachnoid hemorrhage(SAH), 7cases did subdural hematoma(SDH), and 4 cases did epidural hematoma(EDH). On CT re-examination scans, 18 cases showed intracranial hematoma, 8 cases did cerebral contusion and/or laceration, and 6 cases did EDH. Conclusion: Delayed contra coup cerebral injury presents a variety of CT images. It’s necessary to take CT re-examination, particularly for the patients with cerebral contusion and/or Laceration and for the patients with SAH on first CT scan. The optimal time for CT re-examination is in three days after trauma.
