目的：探讨大脑胼胝体发育不全的CT和MRI影像学表现。方法对29例经CT或MRI检查诊断为胼胝体发育不全的影像学表现进行回顾性分析。结果胼胝体发育不全的CT和MRI诊断要点：（1）半球间裂异常靠近第三脑室前部；（2）侧脑室体部平行、分离；（3）第三脑室扩张并向上向前移位；（4）侧脑室枕角扩大；（5）侧脑室额角呈倒“八”字形分离结论根据CT和MRI的特征表现，均可对胼胝体发育不全作出诊断；MRI多平面扫描可更直观地显示胼胝体的发育异常，有利于鉴别诊断。
目的：探討大腦胼胝體髮育不全的CT和MRI影像學錶現。方法對29例經CT或MRI檢查診斷為胼胝體髮育不全的影像學錶現進行迴顧性分析。結果胼胝體髮育不全的CT和MRI診斷要點：（1）半毬間裂異常靠近第三腦室前部；（2）側腦室體部平行、分離；（3）第三腦室擴張併嚮上嚮前移位；（4）側腦室枕角擴大；（5）側腦室額角呈倒“八”字形分離結論根據CT和MRI的特徵錶現，均可對胼胝體髮育不全作齣診斷；MRI多平麵掃描可更直觀地顯示胼胝體的髮育異常，有利于鑒彆診斷。

Objective To study the CT and MRI findings of dysgenesis of the corpus callosum. Methods The CT and MRI findings in 29 pediatric and adult cases with corpus callosum dysplasia were reviewed. Results CT and MRI diagnostic criteria of corpus callosum dysplasia were:(1)abnormal proximity of interhemispheric fissure to the anterior part of the third ventricle;(2) nearly parallel separation of the bodies of the lateral ventricles;(3)dilatation and anterior displacement of the third ventricle;(4) enlarged occipital horns of the lateral ventricles. Conclusions Correct diagnosis of corpus callosum dysplasia could be made on the basis of CT and MRI characteristics,but MRI might directly reveal the developmental abnormality of the corpus callosum on many plane scans,making MRI i the best method to diagnose the dysgenesis of the corpus callosum.
