 There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is sulcal FLAIR hyperintensity, likely relating to sedation and/or oxygenation. There is ill-defined FLAIR hyperintensity in the right parietal centrum semiovale and right parietal periventricular white matter. 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 skull and scalp soft tissues are unremarkable. There is mild maxillary sinus thickening. Aerated secretions are visualized in the sphenoid sinuses with patchy ethmoid opacification.The internal auditory canals are hypoplastic bilaterally, with more conspicuous narrowing of the mid to lateral left canal on the sagittal oblique images. The seventh and eighth cranial nerves are visualized on the right. The left eighth cranial nerve is visualized, although the left seventh cranial nerve is not well delineated, likely due to the small caliber of the internal auditory canal. There is no evidence of mass lesions. The inner ear structures, including the cochlea, vestibule, endolymphatic duct, and semicircular canals, appear unremarkable. No significant abnormal enhancement is seen along the facial nerves.There is incidental mild disconjugate gaze, for which correlation with physical exam is recommended.
1. Hypoplasia of both internal auditory canals, with cochlear nerves seen bilaterally. Likely due to small caliber of the IACs, the intracanalicular left facial nerve is not as well delineated. No definite facial nerve mass or abnormal enhancement.2. Nonspecific nonenhancing right parietal white matter FLAIR hyperintensity, which may represent an area of gliosis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
