Abstract

Purpose: Foster Kennedy described a syndrome of ipsilateral optic atrophy & contralateral optic disc edema, characteristic of an intracranial lesion in the frontal lobe, here we report a rare case of FKS caused by JNA.

Case Report: A 12 yr old boy presented with proptosis LE with history of epistaxis. His presenting visual acuity: OD PL present, OS PL absent, OU pupils dilated & non reactive. Fundus: OD disc oedema, OS Optic Atrophy. Olfactory nerve function was absent. MRI Brain & Orbit: a large lobulated lesion involving left side nasopharynx extending till cavernous sinus causing compression of optic canal.

Discussion: JNA is a rare benign locally aggressive tumour of the nasopharynx that occurs in the age group of 10 -25 years. It occurs in 1 in 150,000 individuals. FKS is believed to be caused by raised intracranial pressure leading to ipsilateral optic atrophy & contralateral disc oedema but in our case FKS was a result of bilateral asymmetric optic nerve compression.
