Meningioma

Case contributed by Austin Neuropathology

Presentation

Increasing headaches.

CT

A somewhat hyperdense enhancing mass is located peripherally in the right frontal region with extensive vasogenic oedema. 

MRI

MRI demonstrates an extradural mass with heterogenous enhancement is surrounded by extensive vasogenic oedema. Other smaller meningiomata are seen at right temporal, right frontal and right parietal para sagittal regions.

Case Discussion

 Although brain oedema was once thought to represent brain invasion this is now known not to be the case. Compression with venous hypertension, rapid growth and local vasoactive factors are thought to play a part. 

At craniotomy the mass was separate from the brain, with an intact pial layer. 

Histology confirmed a meningioma.
