Pseudo-Foster Kennedy syndrome due to idiopathic intracranial hypertension
Foster Kennedy syndrome is characterized by optic atrophy in one eye and papilledema in the other caused by a frontal lobe mass ipsilateral to the atrophic optic nerve. It was first described by Foster Kennedy in 1911 in a case series of 6 patients with expanding frontal lobe lesions.1 Foster Kennedy syndrome is thought to be present in 1% to 2.5% of intracranial masses.2
