CT, axial (A) and coronal (B) planes: Internal auditory canal is flared, labyrinthine portion of facial canal enlarged (lance) and geniculate fossa expanded (arrowheads) by a soft tissue mass (star) protruding posteriorly into the epitympanum, where ossicles are laterally displaced but normally shaped.

MR post-gadolinium SE T1 axial plane: extra-axial bilobed enhancing mass, involving the right cerebellopontine angle cistern (star), internal auditory canal (not shown on this plane), labyrinthine (arrowhead) and geniculate portion (arrow) of the facial nerve. In this not fat-saturated pulse sequence the mass blurs with marrow in the petrous apex (lance).
