Pneumosinus dilatans Presenting with Optic Atrophy in a Gambian Adolescent

Abstract

Pneumosinus dilatans is an abnormal but benign expansion of one or more of the paranasal sinuses, as a result of hyperpneumatization. Though it is often asymptomatic and diagnosed incidentally on imaging of the cranium. Rarely, it presents with ocular, neurological, cosmetic or rhinological complications. Pneumosinus dilatans has the potential to cause progressive and irreversible vision loss.
