Presented by: Dr. Roy Rhodes - Robert Wood Johnson University Hospital


Clinical History:

A 61-year-old woman presented with headache, weakness and gait changes.  A foramen magnum dura-based mass was found by imaging and resected. 

Diagnostic Notes:


Sections showed and EMA-positive meningioma with prominent blood vessels.  Is this:

  1. The usual appearance of an angiomatous meningioma
  2. Meningioma with more clustered, back-to-back blood vessels than usual
  3. Meningioma with intermixed vascular malformation?

It was concluded that the lesion is a spectrum of #1-3.
