Description
Summary:Dandy-Walker malformation and agenesis of the corpus callosum, although uncommon among all births, are commonly seen in association with one another due to the malformations’ effects on the central nervous system. Obstetric sonographers are likely familiar with the typical appearance of these abnormalities in utero, as sonography is routinely used to detect such congenital anomalies prenatally. However, sonography also plays a valuable role in the postnatal follow-up evaluation of the brain and other body systems affected by Dandy-Walker malformation and its associated abnormalities, thus making it imperative for all sonographers to be familiar with their postnatal sonographic appearance. The case presented demonstrates the use of neonatal sonography to evaluate and follow a case of Dandy-Walker malformation with associated agenesis of the corpus callosum that was originally diagnosed by prenatal sonography. The purpose of this case study is to highlight the pathologies and their coexistence, demonstrate their neonatal sonographic characteristics, exhibit corresponding magnetic resonance imaging appearance, and provide guidance for future patient cases.
