The signal intensity (SI) of the labyrinth in patients with vestibular schwannoma (VS) is known to be increased on FLAIR MRI due to increased protein concentration within the perilymph. We compared SI changes of the cochlear in patients with cerebellopontine angle (CPA) meningioma with VS on 3D FLAIR imaging.
