Methods Between January 2014 and December 2019, 268 fetuses, mean gestational age of 28.3 weeks (range 22-40 weeks), with mild ventriculomegaly and diaphanous diaphragm reduction or disappearance diagnosed at prenatal sonography were included in this study. Conclusion Detailed fetal sonography combined with fast MRI can accurately diagnose fetal ACC, especially improve the detection rate of partial corpus callosum agenesis, and provide a reliable basis for clinical diagnosis, especially in fetues with mild ventriculomegaly and CSP reduction/disappearance in routine ultrasonic examination. Figure 1Spear-shaped ventricles, non-visualization of CSP, elevated third ventricle (used to be mistaken for CSP), etc could be visible in US and MRI. The CC-arterty coursevariation could be dected in US-CDFI and the Radial cortical sulcation only in MRI.
