Pseudo Foster-Kennedy Syndrome in an amblyopic patient: a case report

TL;DR

This case report describes a patient with pseudo-Foster-Kennedy syndrome, a condition mimicking a neurological disorder but without a brain mass.

Contribution

The novelty lies in presenting a rare case of pseudo-Foster-Kennedy syndrome caused by amblyopia and optic atrophy.

Findings

The patient exhibited optic disc swelling in one eye and optic atrophy in the other.

Diagnosis was confirmed through detailed medical history and examinations.

The condition was attributed to sequential bilateral NAION rather than an intracranial mass.

Abstract

Pseudo-Foster-Kennedy syndrome presents with optic disc swelling in one eye and optic atrophy in the other eye. It differs from the true Foster-Kennedy syndrome due to the absence of an intracranial mass. One of the most common causes of pseudo-Foster-Kennedy syndrome is sequential bilateral NAION.

We present the case of a male patient who came to the emergency room in our clinic complaining of sudden vision loss in his right eye, headache, and hearing loss. The patient also had a diagnosis of high amblyopia in his left eye, where we also discovered an optic atrophy. We established the positive diagnosis of pseudo-Foster-Kennedy syndrome after a thorough anamnesis, ophthalmologic examination, and multiple investigations.
