脑干梗塞临床及影像学检查分析

目的：探讨脑千梗塞的临床症状与CT、MRI等影像学检查结果的关系。方法：对脑干梗塞病例的影像学检查结果与临床症状进行对比分析，观察临床症状与病灶的位置间的关系。结果：脑干梗塞的症状与部位之间有一定的特异性：脑干梗塞时前庭核团最易受损，所以眩晕症状最为常见；脑桥上部小的梗塞灶可以无症状，而中下部桥脑病变可导致明显的肢体瘫痪；中脑易致消化道出血；中脑及延病变易致球麻痹：在对脑干梗塞的检出率方面，MRI明显高于CT。结论：可以利用脑干梗塞的症状与病灶部位间的关系并结合影像学检查提高脑干病变的检出率。

Analysis clinical symptom and results of imaging examination in brian stem infarction

Objective: To demonstrate the association of clinical symptom and results of imaging examination in brain stem infarction.Method: To analyse the imaging results and their clinical symptom in 61 patient of brain stem infarction, and to discover the relationship of symptom and position.Result: There are some specificities in the position and symptom. Nucleuses of vestibule is easiest spot to be damaged in Brain stem infarction, so the symptom of vertigo is the commonest. There will be no symptom in the patients who have little infarction in the upper of pontine, but paralysis of body is easily to be found when the infarction locates in the middle or bottom. Infarction occurred in mesencephalon can cause bleeding of digestive tract easily. Bulbar paralysis is common in the infarction of medulla oblongata and mesencephalon. In diagnoses of Brain stem infarction, MRI is more superior than CT.Conclusion: We can use the relationship of the symptom and location to improve the rate of diagnoses in brain stem infarction.
