Pediatric Spine Tumors and Dysontogenetic Masses

Abstract

The pediatric spine undergoes complex stages of development and growth, resulting in highly age-dependent physiology and variable susceptibility to certain pathologies. Optimal radiologic evaluation requires image acquisition tailored to the clinical history and an interpretive approach that accounts for demographic variations. In this article, the author discusses the diagnostic approach to pediatric spine masses, beginning with a discussion of normal anatomy and variants, clinical evaluation, and imaging techniques and protocols. The author then covers the major etiologies, imaging appearances, and mimics of pediatric spine masses in the following categories: congenital malformations, genetic syndromes, intramedullary, intradural, epidural, bone, and paraspinal lesions.
