Fetal and Neonatal Brain Tumors: An Imaging Review

Congenital brain tumors (CBTs) are neoplasms detected during fetal life or early neonatal life. These are exceedingly rare and account for 0.5% to 1.5% of all pediatric brain tumors. CBTs are histologically distinct and clinically more aggressive than other pediatric brain tumors. Advances and increased availability of neuroimaging has enabled early and accurate detection of these lesions and associated complications, allowing clinicians to manage pregnancy and neonatal care and better plan and prepare for interventions in advance. In this article, we provide an overview of the incidence, pathogenesis, and clinical presentation of some common CBTs along with their imaging manifestations.
