Fetal corpus callosum abnormalities: Ultrasound and magnetic resonance imaging role

Behnaz Moradi et al. J Clin Ultrasound. 2022 Sep.

Abstract

The corpus callosum (CC) is the major interhemispheric commissure and its abnormalities include agenesis, hypoplasia, and hyperplasia. The CC anomalies are typically related to other central nervous system (CNS) or extra-CNS malformations. The antenatal diagnosis of complete CC agenesis is easy after mid-trimester by ultrasound (US) even in the axial plane. The non-visualization of cavum septum pellucidum and colpocephaly are critical signs in the axial view. More subtle findings (i.e., hypoplasia and partial agenesis) might also be recognized antenatally. In this review, the focus was given on the prenatal diagnosis of CC abnormalities in US and magnetic resonance imaging.

Keywords: corpus callosum; magnetic resonance imaging; prenatal diagnosis; ultrasound.
