Increased 3D-FLAIR postgadolinium signal intensity of the ipsilateral labyrinth associated with vestibular schwannoma was shown to be correlated with sensorineural hearing loss. The study found that measured intralabyrinthine signal is associated with greater degrees of sensorineural hearing loss on audiometry.

This systematic review and meta-analysis aimed to determine whether the presence of IVLs and CN VIII NVC on MRI is associated with tinnitus, SNHL, or vertigo and any specific subtypes. It was found that CN VIII NVC is associated with vestibular paroxysmia, and IVL is associated with sudden-onset SNHL. No association was found between IVL or CN VIII NVC and undefined tinnitus, SNHL, and vertigo.
