The neuroradiologic evaluation of "optic neuritis".

Abstract

Optic neuritis, even when clinically typical, cannot be diagnosed with certainty because mass lesions compressing the anterior visual pathways may mimic it. The radiologist is in a position to assist in identifying such lesions or in ruling them out and thus preventing surgical exploration. While every patient in whom the diagnosis of optic neuritis is entertained should have plain roentgenograms of skull, orbits and optic canals, we have developed a schema for detailed neuroradiologic investigation based on clinical and plain roentgenographic findings. A classification of such lesions by location is illustrated.
