NF1 with impairment of acuity and macrocephaly with mental retardation. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a small left medial orbitofrontal gyrus developmental venous anomaly. The brain parenchyma otherwise appears unremarkable. The lateral ventricles are perhaps mildly prominent, particularly on the right side. 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.Orbits: The bilateral intraorbital optic nerves are somewhat tortuous, but do not appear to be thickened or display abnormal signal or enhancement. The bilateral globes and ocular adnexa are unremarkable. There is no evidence of abnormal intraorbital enhancement or mass lesions.
1. The bilateral intraorbital optic nerves are somewhat tortuous, but no definite evidence of optic nerve glioma.2. No intracranial stigmata of neurofibromatosis type 1 other than perhaps mildly prominent lateral ventricles.
