Left sensorineural hearing loss. 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 is a cystic pineal gland that measures up to approximately 15 mm. There is diffuse volume loss of the imaged portions of the brain parenchyma.
1. No evidence of retrocochlear or inner ear lesions.2. A cystic pineal gland that measures up to approximately 15 mm likely represents benign cystic degeneration.
