History of cerebellopontine angle meningioma status post surgical resection and radiotherapy. Follow-up exam. There are postsurgical findings related to right suboccipital craniotomy and resection of the right cerebellopontine angle meningioma. There is unchanged mild dural enhancement along the posterior aspect of the right petrous apex, as well as minimal patchy enhancement in the right cerebellar hemisphere, but no discernible residual mass lesion is identified. There is persistent flattening of the right cerebellar hemisphere. There is mild patchy periventricular and subcortical white matter T2 hyperintensities and a chronic right corona radiata lacunar infarct, but no acute ischemic infarct. There is a left parietal developmental venous anomaly. The ventricles and basal cisterns are stable in size and configuration. There is trace fluid in the mastoid air cells.
Stable postsurgical findings related to prior surgical resection of a right cerebellopontine angle meningioma without gross residual or recurrent tumor.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
