Cerebellopontine angle meningioma

Case contributed by Assoc Prof Frank Gaillard

Selected images from a non-contrast CT demonstrate a right hyperdense cerebellopontine angle mass. The periphery of the mass is 95HU in density. Centrally it appears more dense, likely calcified. 

Selected images from an MRI demonstrate a vividly enhancing extra-axial mass posterior to the internal acoustic meatus. It is isointense to adjacent cerebellum on both T1 and T2 weighted images. The seventh and eighth cranial nerves are clearly separate. 

Findings are most consistent with a meningioma.
