Case Author: Frank J. Minja, MD, Yale University School of Medicine


13-year-old girl with progressive lower extremity weakness.

Imaging Findings

Sagittal (A) and axial (B) T2-weighted MR images show an expansile T2-hyperintense lesion at T6 involving the vertebral body and posterior elements with preserved vertebral body height and internal trabeculation. Also evident is a circumferential epidural component that results in severe central spinal canal stenosis. Sagittal unenhanced (C) and contrast-enhanced (D) T1- weighted MR images show avid contrast enhancement of the expansile lesion and the epidural component.
