title: Clinical and computed tomographic findings in the Foster Kennedy syndrome.
abstract: A 52-year-old man had progressive loss of visual acuity in his left eye associated with anosmia of five years duration. Clinical findings included papilledema in the right eye and optic atrophy in the left eye. A diagnosis of Foster Kennedy syndrome was made. Careful attention to the ophthalmoscopic appearance of the left eye disclosed optic disk swelling in regions without significant atrophy as well as dilated retinal veins. Both of these signs suggested increased intracranial pressure, rather than a primary anterior ischemic optic neuropathy. High resolution computed tomographic scanning confirmed the presence of a large subfrontal meningioma and an expanded right optic nerve sheath, consistent with the papilledema noted clinically.
