NF type 1, failed vision testing, headaches. Orbits: The optic nerve are not enlarged and display normal signal characteristics. The bilateral optic nerve discs appear to be slightly prominent and there may be mild staphylomatous deformity of the globes. The extraocular muscles, lacrimal glands, and orbital fat otherwise appear to be intact bilaterally. There is no evidence of abnormal intraorbital enhancement or tumors. Brain: There appears to be a punctate focus of high T2 signal in the left posterior thalamus. The brain parenchyma otherwise appears unremarkable. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The lateral ventricles are asymmetric, in which the right is slightly smaller than the left. 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. The bilateral optic nerve discs appear to be slightly prominent, but there is no evidence of optic nerve gliomas otherwise.2. An apparent punctate focus of high T2 signal in the left posterior thalamus may represent a stigmata of neurofibromatosis type 1.
