Right auditory nerve schwannoma: dizziness, tinnitus, and right-sided hearing loss There is a punctate focus of restricted diffusion and high T2 signal in the posterior aspect of the left cerebellar hemisphere, compatible with acute infarct. There are also a few scattered periventricular and subcortical white matter T2 hyperintense foci without restricted diffusion. There is an avidly enhancing tubular lesion in the right internal auditory canal that measures up to approximately 10 mm. There is no evidence of acute intracranial hemorrhage. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.Punctate acute infarct in the left posterior cerebellar hemisphere. 2.Unchanged right vestibular schwannoma.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
