A Silent Corticotropic Pituitary Adenoma with Foster Kennedy Syndrome: A Case Report

Abstract

Foster Kennedy Syndrome is unilateral optic disc swelling with contralateral optic atrophy, usually due to a frontal lobe tumour compressing the optic nerve on one side and resulting in papilloedema contralaterally. The etiological and topographical diagnosis uses brain imaging. We describe a case of a silent corticotropic pituitary adenoma associated to a Foster Kennedy syndrome in a 57 years old man. To the best of authors’ knowledge, this is the fourth case report regarding pituitary adenoma presenting with Foster Kennedy syndrome. We reviewed the pathogenesis and common clinical manifestations of Foster Kennedy syndrome and would like to highlight the role of neuroimaging techniques in the diagnosis.
