Tinnitus, bilateral [H93.13], Reason for Study: ^Reason: acustic schwannoma History: tinnitus No evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.The brainstem, cerebellum, vermis and tonsils are normal. The inner ear structures, cochlea, vestibule, semicircular labyrinth are normal. The internal auditory canals are normal with delineation of the facial, cochlear and vestibular nerves. No evidence of signal abnormality, mass or abnormal enhancement is noted. The ventricles, cerebral sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast-enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Normal brain MRI.Normal internal auditory canal on this MRI scan.If indicated, temporal bone CT scan can be considered for further imaging evaluation.
