1 A, Coronal enhanced MR image of an IAC meningioma demonstrates intense enhancement of the intralabyrinthine structures (curved white arrow). A, Coronal enhanced MR image of an IAC meningioma demonstrates intense enhancement of the intralabyrinthine structures (curved white arrow). The mass extends from the IAC and cerebellopontine angle (open white arrow).B, Axial enhanced MR image of an IAC meningioma demonstrates intense enhancement of the cochlea (curved white arrow) and vestibular apparatus (open white arrow). The large IAC and cerebellopontine angle enhancing mass (straight white arrow) are clues to the diagnosis. B.E. Hamilton et al.
