68-year-old female with a cerebellopontine angle meningioma status post surgical resection and radiotherapy. Follow-up exam.. Postsurgical changes related to right suboccipital craniotomy and CP angle tumor resection are unchanged. A small amount of T2/FLAIR hyperintensity along the right cerebellum and right middle cerebellar peduncle are stable. There is persistent flattening of the right cerebellar hemisphere and a prominence of the extra-axial space in this location. Mild dural enhancement along the posterior aspect of the petrous apex is stable. No residual mass lesion is identified in the area of resection. There has been interval development of a subcentimeter focus of susceptibility artifact in the posterior limb of the left internal capsule. Mild patchy periventricular and subcortical white matter T2 hyperintensities and the prior right corona radiata lacunar infarct are stable. There is no evidence of acute ischemic infarct. There is a left parietal developmental venous anomaly. There is a 10 x 5 mm extra-axial lesion along the left occipital lobe that is T1 isointense, mildly T2 hyperintense and avidly enhancing with a dural tail. This is stable in size and appearance since 7/16/2014.The ventricles and basal cisterns are stable in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.Stable postsurgical changes related to right cerebellopontine angle meningioma resection. There is no evidence of residual or recurrent tumor.2.Stable 10 x 5 mm left occipital meningioma, even dating back to baseline exam.3.Interval punctate hemosiderin staining in the posterior limb of left internal capsule related to trace hemosiderin.
