Binasal hemianopia caused by pneumosinus dilatans of the sphenoid sinuses

Abstract

Bitemporal hemianopia is a significant pathological hallmark of a pituitary lesion; however, binasal hemianopia is rarely reported, except for its known association with other ocular diseases rather than with brain lesions. We report a 24-year-old male with binasal hemianopia caused by pneumosinus dilatans of the sphenoid sinuses.
