Assess for vascular malformations compressing IAC nerve bundles: vertigo and noise in the left ear. Internal Auditory Canals MRI: The bilateral cranial nerve 7 and 8 complexes are intact. There is no evidence of mass lesions. The inner ear structures, including the cochlea, vestibule, endolymphatic duct, and semicircular canals, appear unremarkable. The bilateral mastoid air cells and middle ears also appear unremarkable. There are secretions within the right maxillary sinus.Brain MRA: There is no evidence of significant steno-occlusive lesions, aneurysms, or vascular malformations. There is an accessory left superior cerebellar artery, which is a normal variant.
No evidence of lesions compromising the internal auditory canal contents.
