NF1 and optic glioma. BRAIN: There is an unchanged patchy area of T2 hyperintensity within left cerebellar hemisphere. There are also unchanged areas of T2 hyperintensity in bilateral parietal periventricular white matter, hypothalamus, and posterior right putamen. There is no associated abnormal enhancement. The pons and corpus callosum are unchanged. The optic chiasm is not enlarged. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The cerebral flow voids appear to be grossly intact. There are inflammatory changed within the left sphenoid sinus.ORBITS: There is unchanged enlargement of the intraorbital and perhaps the intracanalicular portions of the left optic nerve up to approximately 3 mm in width, with mild T2 hyperintensity and negligible enhancement. The right optic nerve appears to be normal. In addition, the globes, extraocular muscles, lacrimal glands, retrobulbar fat, and preseptal soft tissues are normal bilaterally.
1. Unchanged intracranial stigmata of neurofibromatosis type 1.2. No significant interval change in the small left optic nerve glioma.
