Hearing loss and right cochlear implant, which was partly removed for the MRI exam. Internal Auditory Canal: There is right retrosigmoid and mastoid air cell fluid related to recent removal of a portion of the right cochlear implant components, with electrodes that remain within the right cochlea. Otherwise, there is no evidence of gross inner ear anomalies bilaterally and 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 left mastoid air cells and middle ears appear unremarkable.Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain, brainstem, cerebellum, and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable. There are secretions in the right anterior ethmoid sinuses.
Findings related to recent removal of a portion of the right cochlear implant components, but no evidence of cochlear nerve deficiency or gross structural brain anomalies.
