Of the 19 cases,19 fetus were found,MRI confirmed 14 cases considered or suspected as fetal corpus callosum agenesis by US(8 cases are completed agenesis of corpus collosom-CACC,6 cases are partial agenesis of corpus collosom-PACC, and 5 cases had took on autopsy),however 3 cases are mild enlargement of lateral cerebral ventricle and 2 cases are leukodystrophy.In these cases,MRI confirmed a Dandy-Walker syndrome and a lipoma of corpus callosum suspected by US,detect a Dandy-Walker syndrome and a microcephalus made missed diagnoses by US.The fetal corpus callosum and additional cerebral anomalies were shown more clearly on MR T_2-weighted images.

Patients with mech-anical injuries to corpus callosum, e,g., tumor compression, anterior or posterior cerebral artery infarction may have in neurological defects including left apraxia, left alexia or anomia to colors. Nevertheless, these symptoms may not occur in congenital corpus callosum agenesis, complete or incomplete.

胼胝体的后天缺损常造成患者左侧失用症及左侧失读症等右大脑无法取得左大脑资讯的症状；然而先天性胼胝体完全或部分缺损（complete or incomplete congenital corpus callosum agenesis）却不见得会有这些症状，相对的，它伴随其他症候群的机会则很大。

The corpus callosum is not isible in the standard transerse iews of the brain but agenesis of the corpus callosum may be suspected by the absence of the caum septum pellucidum and the 'teardrop' configuration of the lateral entricles (enlargement of the posterior horns).

诊断：正常在脑的标准横切面上看不到胼胝体，通常通过透明隔腔小时和侧脑室的泪滴状改变怀疑有胼胝体的发育不良，确诊胼胝体发育不良需要在正中冠状面和正中矢状面上，一般需要做阴道B超显示。

To evaluate normal development and anomalies of corpus callosum in childhood, magnetic resonance images of 149 children and 20 adults with normal findings were collected to measure the thickness of genu, body and splenium and the length of corpus callosum on the midsagittal T1-weighted images.

我们选择脑部磁振造影所见正常之149位病童及20位成人，由T1为主的(T1-weighted)正中矢状面影像，测定胼胝体在膝部、体部及压部之厚度，胼胝体长度，以及脑前后径。

Results: ADC in MS group was increased in all regions of NAWM compared to controls(P＜0.05),significantly higher in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.01). FA value in MS group was decreased in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.05), the genu and splenium of CC,middle cerebellar peduncle showed an insignificant trend of lower FA.

结果：MS组的正常表现脑白质的ADC值均高于对照组(P＜0.05)，以胼胝体体部、内囊、侧脑室旁及额、顶、枕叶脑白质更为显著(P＜0.01)；MS组的FA值与对照组比较，胼胝体体部、顶、额、枕叶白质及内囊、侧脑室旁发现明显降低(P＜0.05)，以后4个部位更为显著(P＜0.01)，而胼胝体膝部、压部和小脑结合臂有降低趋势，但无统计学意义。

In about 90% of those with apparently isolated agenesis of the corpus callosum deelopment is normal.

预后：取决于病因，90%明显的单纯性胼胝体发育不全是正常的。

Several cases of congenital agenesis of the corpus callosum have been reported in the literature, and it is clear that this deformity need not result in language learning difficulties.

据文献上的报导，有几个先天胼胝体发育不全的案例，而这种缺陷对导致语言学习的困难不是必要的。

Other midline cystic abnormalities may be associated with more complex malformations, such as agenesis of the corpus callosum with an interhemispheric cyst.

其他的中线部囊性异常可以与更为复杂的畸形有关，如伴有大脑半球之间囊肿的胼胝体发育不全。
