Vestibulocochlear schwannoma. A, Axial high-resolution FSE T2-weighted MR image (4000 ms/102 ms/6 [TR/TE/NEX]) at the level of the cochlea and vestibule reveals a hypointense filling defect within the cochlea (arrow) and vestibule (curved arrow), replacing the normal hyperintense CSF signal intensity, representing the vestibulocochlear schwannoma. B, Axial enhanced T1-weighted MR image (800 ms/72 ms/2 [TR/TE/NEX]) at the level of the cochlea and vestibule reveals a homogeneously enhancing mass in the cochlea (arrow) and vestibule (curved arrow), which corresponds to the T2 abnormality, representing the vestibulocochlear schwannoma. C, Coronal enhanced T1-weighted MR image (800 ms/72 ms/2 [TR/TE/NEX]) at the level of the cochlea and vestibule reveals a homogeneously enhancing mass nearly filling the cochlea (arrow), representing the vestibulocochlear schwannoma.
