Suspected left ischemic optic neuropathy after cataract extraction and history of Neurofibromatosis type 1. There are bilateral lens implants. The globe contents are otherwise grossly unremarkable. The bilaterally optic nerves are not enlarged and do not display discernible abnormal enhancement. There is no evidence of mass lesions within the bilateral orbits. The lacrimal glands, intraorbital vessels, extraocular muscles, and orbital fat appear unremarkable bilaterally. The optic chiasm and cavernous sinuses are intact. There are punctate enhancing skin nodules in the temporal scalp regions bilaterally. The imaged portions of the intracranial structures are unremarkable.
1. Bilateral lens implants, but no evidence of optic nerve or orbital lesions. However, MRI is generally not very sensitive for detecting small ischemic lesions of the optic nerves.2. Punctate enhancing skin nodules in the temporal scalp regions bilaterally likely represent neurofibromas in the setting of Neurofibromatosis type 1.
