# 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.

## Key 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.
