Fetal imaging of posterior fossa malformations

Toan Nguyen et al. Pediatr Radiol. 2025 Apr.

Abstract

Posterior fossa anomalies are less common in prenatal diagnosis than midline anomalies or ventricular dilatations. However, they constitute an important entity, combining neurological disorders as well as normal variants that should be recognized in prenatal diagnosis because of the genetic implications and neurodevelopmental outcome of some of these conditions. Here we present some of the main imaging features enabling prenatal diagnosis of posterior fossa anomalies in a context of constantly evolving classifications, resulting from advances in genetics and neuroimaging.

Keywords: Cerebellum; Cranial fossa; Magnetic resonance imaging; Posterior; Prenatal; Ultrasound.
