Radiologic-Pathologic Correlation of Pediatric and Adolescent Spinal Neoplasms: Part 2, Intradural Extramedullary Spinal Neoplasms

OBJECTIVE. The purpose of this article is to review the neuroimaging findings of intradural extramedullary spinal tumors in the pediatric and adolescent population. The differential diagnosis for lesions in this location is limited and can be further narrowed with knowledge of specific imaging characteristics. CONCLUSION. This article reviews the radiologic and pathologic findings of pediatric and adolescent intradural extramedullary neoplasms. After completing this article, the reader should have an improved understanding of the types of neoplastic processes that involve the extramedullary intradural compartment of the spine in the pediatric and adolescent age groups and should be able to narrow their differential diagnosis according to imaging findings.
