胼胝体（corpus callosum，CC）是连接两个大脑半球新皮质区的最大的纵裂连合。CC的异常范围包括发育不全（可能是完全或部分）和发育不全。胼胝体发育不全可能是孤立的，也可能与其他异常有关。透明隔腔显影不清和阴道头畸形是辅助诊断的重要征象。证明正中矢状面无CC是金标准。我们报告一个孤立的完全胼胝体发育不全的情况下，产前诊断在孕晚期与胼胝体发育不全的超声表现进行了简要的审查。
The corpus callosum (CC) is the largest interhemispheric commissure connecting the neocortical areas of the two cerebral hemispheres. The spectrum of anomalies of the CC includes agenesis, which may be complete or partial, and hypoplasia. The callosal agenesis may be isolated or may be associated with other abnormalities. Nonvisualization of cavum septum pellucidum and colpocephaly are important signs in the axial view which aid in the diagnosis. Demonstrating the absence of CC in midsagittal plane is the gold standard. We report a case of isolated complete corpus callosal agenesis diagnosed antenatally in the third trimester with a brief review of ultrasound findings in corpus callosal agenesis.
