摘　　要：目的探讨一侧颞顶叶急性脑梗死时胼胝体形态可能存在的变化。方法连续采集发生于一侧颞叶、顶叶或2个部位均有的急性脑梗死患者66例，男38例，女28例，年龄40-85岁。选取同期连续采集获得的与病变组匹配的66例正常成人作为对照分析组。行磁共振扫描，在MRIT1WI颅脑正中矢状位上分别测量胼胝体膝部厚度、体部前1／3处厚度、中部厚度、体后1／3处厚度、压部厚度及胼胝体面积，进行统计分析研究。结果所测量的胼胝体膝部厚度、体部前1／3处厚度、中部厚度、体后1／3处厚度、压部厚度及胼胝体面积值，均为正常组大于病变组，且这些指标在正常组和病变组之间差异均存在统计学意义（P〈0．05）。结论当大脑一侧脑叶发生急性脑梗死时，即可引起胼胝体面积及不同区域大小的减小。Objective To study the changes of morphology of corpus callosum with acute cerebral infarction. Methods Sixty-six patients with acute cerebral infarction in temporal and/or partial lobe were collected consecutively. There were 38 men and 28 women. Age ranged from 40-85 years old. Sixty-six match healthy adult volunteers were collected consecutively as control group in the same period. All cases underwent MR scan, and the thickness of the genu, anterior one-third, middle part, posterior one-third, splenium and the area of the corpus callosum were measured on MRI T1WI middle sagittal section images and statistic analysis was performed. Results The thickness of the genu, anterior one-third, middle part, posterior one-third, splenium and the area of the corpus callosum were decreased in infarction group compared with that in control group, and there were significant differences between them（P〈0.05）. Conclusion The area and the thickness of different parts of the corpus callosum are totally decreased in acute cerebral infarction of unilateral hemisphere.
