Radiography
Scoliosis
Widening of the spinal canal
CT
Isodense or slightly hyperdense intracanalar vertebral mass, markedly enhancing after injection
MRI
Generally well-defined tumor
Generally iso- or hypointense on T1 relative to the spinal cord
Possible T1 hyperintensity due to recent hemorrhage
Hyper- or isointense on T2
Hypointense T2 rim = hemosiderin deposits at the tumor poles from prior bleeding
Spinal cord edema
Marked enhancement after gadolinium injection
Look for dural seeding on the post-contrast sequence
Differential diagnosis
Astrocytoma
