Overview

Imaging plays a central role in the diagnosis of ependymoma. On MRI brain, ependymoma is characterized by isointense to hypointense on T1-weighted scans, or hyperintense to white matter on T2-weighted MRI.

MRI

Brain

  • T1
    • Solid portions of ependymoma typically are isointense to hypointense relative to white matter
  • T2
    • Hyper intense to white matter
    • More reliable in differentiating tumor margins than non-contrast T1-weighted images (but less reliable than contrast enhanced T1)
