摘要
目的比较MR、CT和体格检查在脑干损伤早期诊断中的作用。方法将颅脑损伤后出现意识障碍需排除脑干损伤的21例患者在保持气道通畅等情况下，进行体格检查、CT和MR检查，并对诊断结果进行对比分析。结果本组21例颅脑损伤后意识昏迷患者中出现脑干损伤症状17例，行气管切开14例，行颅内血肿或脑挫伤减压手术7例。21例均行头颅CT检查示脑干区低密度影9例，广泛性蛛网膜下腔出血或环池周围出血7例，轻度蛛网膜下腔出血表现或脑干周围变化不明显5例；头颅MRJ检查证实脑干损伤15例，另6例仅为纵裂、颅底、半球区脑挫伤。结论MRI对于脑干损伤的诊断优于CT及体格检查，可起到确诊作用。
Objective To compare the prognostic role of MRI scan, CT scan and physical check-up in the brainstem injury. Methods Twenty-one patients with craniocerebral injury, appearing disturbance of consciousness, were performed MRI scan, CT scan and physical check-up to exclude brainstem injury under airway unobstructed condition; their results were compared and analyzed. Results In all of these patients, 17 showed brainstem injury symptoms. Tracheotomy was performed in 14 and decompression of cerebral contusion and removal of intracranial hematoma was performed in 7. CT examination was adopted in all the patients： low-density shadow in brainstem region and catholicity subarachnoid hemorrhage was found in 9 and 7, respectively; gently subarachnoid hemorrhage or no obvious brainstem change was noted in 5. MRI scan showed that 15 patients were diagnosed as having brainstem injury and 6 were base of skull or hemisphere region injuries. Conclusion MRI scan, which is better than CT scan and physical check-up, can help to make a definite diagnosis in brainstem injury.
