Agenesis of the corpus callosum

Case contributed by Dr Alexandra Stanislavsky

Presentation

Abnormality on obstetric ultrasound, for further evaluation.

Patient Data

Age: 24w GA
Gender: Female
MRI

Fetal MRI demonstrates complete absence of the corpus callosum, with expected colpocephaly and absence of the cavum septum pellucidum (CSP).

Case Discussion

Typical antenatal MRI appearance of an absent corpus callosum. The diagnosis had been made on a prior tertiary ultrasound scan. The role of fetal MRI in this scenario is to look for associated findings that may alter the prognosis, and may not be seen with ultrasound - such as malformations of cortical development, schizencephaly, posterior fossa malformations.
