17-year-old male with bilateral tinnitus. Evaluate for vestibular schwannoma and inner ear abnormalities. MRI Brain:The brain parenchyma and pituitary gland appear unremarkable. There is no evidence of intracranial hemorrhage, mass, or acute infarct. Specifically no signal abnormality involving the brainstem is appreciated. Postcontrast sequences are motion degraded but grossly unremarkable. 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. There is minimal ethmoid and maxillary sinus mucosal thickening. The remainder of the orbits, skull, and scalp soft tissues are grossly unremarkable. Mastoid air cells are clear.MRI IACs:The internal auditory canals are symmetrical and normal in size and signal intensity. The inner ears are normal, with normal T2 signal and no pathological enhancement. No abnormal mass or abnormal enhancement is seen within the cerebellopontine angle cisterns bilaterally or within the internal auditory canals.
1.Brain parenchyma appears within normal limits. Specifically no signal abnormality involving the brainstem.2.No evidence of vestibular schwannoma or other inner ear abnormality.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
