Foster Kennedy Syndrome

Foster Kennedy Syndrome (Basal-Frontal Syndrome; Gowers-Paton-Kennedy Syndrome)

General:
Caused by tumor in base of frontal lobe or sphenoidal meningioma.

Ocular: Central scotoma may be present on side of optic atrophy; enlarged blind spot and peripheral contraction of field (opposite eye); homolateral descending optic atrophy due to compression of the ipsilateral optic nerve at the optic foramen; contralateral papilledema due to increased intracranial pressure; ipsilateral proptosis.

Clinical: Anosmia; headache; dizziness; vomiting; memory loss; psychic changes; also may be caused by an olfactory groove tumor (usually a meningioma) or pituitary adenoma.
