 Again noted is a circumscribed homogeneously enhancing mass in the left retrobulbar space, encasing the diminutive and medially displaced left optic nerve. The mass measures 2.3 x 1.3 x 1.5 cm, not significant changed since the previous study; however, the mass is decreased in size compared to remote studies, consistent with expected post-treatment change. The mass fills the left orbital apex with complete encasement of the left superior ophthalmic vein. There is stable extension of enhancing tissue into the superior orbital fissure with minimal invasion of the lateral left cavernous sinus. Mild relative left proptosis is unchanged. The right orbit is unremarkable. Extraocular muscles are unremarkable.Scattered the nonspecific T2 hyperintensity is seen in the basal ganglia, which most likely represents prominent perivascular spaces. Again, seen stable plaque like area of dural based enhancement along the right inferior frontal gyrus, unchanged in size since previous study.
1. Stable enhancing left orbital mass encasing the left optic nerve which is diminutive in size and displaced medially. No changes since previous study.2. Also stable appearance of a plaque-like area of enhancement along the right gyrus rectus which likely represents a small intracranial meningioma, seen on multiple prior remote exams.
