Pseudo-Foster Kennedy syndrome is defined as one-sided optic atrophy with papilledema in the other eye but with the absence of a mass.

[5][6] There are other symptoms present in some cases such as nausea and vomiting, memory loss and emotional lability (i.e., frontal lobe signs).

Clinical localization of brain tumors may be possible by virtue of specific neurologic deficits or symptom patterns.

[6] While awaiting surgical removal, treat any increased intracranial pressure with high-dose steroids (i.e., dexamethasone).

[citation needed] The syndrome was first extensively noted by Robert Foster Kennedy in 1911, an Irish neurologist, who spent most of his career working in the United States of America.
