Abnormalities of corpus callosum are one of the most common brain anomalies. Fetuses with isolated corpus callosum agenesis (CCA) have a better prognosis than those with additional anomalies. However, unpredictable neurodevelopmental outcomes of truly isolated CCA make prenatal counseling a challenge. The aim of this review is to evaluate neurodevelopmental outcomes in children with prenatal diagnosis of isolated CCA. Controlled clinical trials published between May 23, 2009, and May 23, 2019, using the MeSH term “agenesis of corpus callosum” were reviewed. A total of 942 articles were identified, and 8 studies were included in the systematic review depending on the inclusion criteria. These studies included 217 fetuses with isolated CCA and no other anomalies at prenatal assessment. Neurodevelopmental outcome was reported to be normal in 83 children with a prenatal diagnosis of isolated CCA confirmed at birth within 128 completed assessments. About 45 children presented borderline, moderate, or severe neurodevelopmental outcome. In this review, neurodevelopment was favorable in two-thirds of the cases, but mild disabilities emerged in older children. Despite this, disabilities can occur later beyond school age and a low risk of severe cognitive impairment exists. Our study highlights the essential early diagnosis and proper supportive therapy.

Abstract Background: The corpus callosum is the main pathway connect the interhemispheric communication. Corpus callosum agenesis from asymptomatic to mild or severe neurodevelopmental disorders. However, few cases have been previously reported in the literature on prenatal diagnosis between corpus callosum agenesis and chromosomes abnormality. The study included prenatal diagnosis of 4 fetuses in whom prenatal ultrasound showed corpus callosum abnormality, isolated or associated with other central nervous lesions.Case presentation: Prenatal diagnoses of four children were summarized in our case. The routine prenatal ultrasound examination showed abnormal morphology of corpus callosum in fetus 1, dysplasia of the corpus callosum in fetus 3, the corpus callosum absence in fetus 2 and fetus 4, and fetus 4 also had cardiac abnormalities. Chromosomal microarray and G-band karyotype analysis were performed to provide genetic analysis of amniotic fluid. The results revealed 4.8M deletion at 1p36.33p36.31 in fetus 1, 3.1M deletion at Xq26.3q27.1 in fetus 2, 6.5M deletion at distal 1q43q44 and a duplication of 8.8M at 7q36.1q36.3 in fetus 3, fetus 4 had a deletion of 9.51M at 1p36.33p36.22 and 14.3M duplication at 6q25.3q27.Conclusion: The genetic mechanism of corpus callosum agenesis is variably complex, and its clinical phenotype may occur either alone or in association with other abnormalities. This study revealed the microabnormalities of multiple chromosomes are related to the corpus callosum abnormality. Combined with ultrasound examination, the application of chromosome microarray analysis will effectively improve the diagnosis of congenital submicroscopic chromosomal abnormalities in fetuses.

A case of prenatal diagnosis of the corpus callosum lipoma at 32–33 weeks of gestation is presented. In a consultative examination, a hyperechoic formation with clear contours was found in the projection of the septum pellucidum, occupying the rostrum, genu, and truncus of corpus callosum, without signs of intratumorally blood flow in the color Doppler mapping mode. The prenatal diagnosis of "callosum lipoma" was established, confirmed after the birth of a child during magnetic resonance imaging.
