Choristoma of the Optic Nerve and Chiasm

Arch Ophthalmol. 1992;110(2):236-238. doi:10.1001/archopht.1992.01080140092034
Abstract

• A 21-year-old patient with a biopsyproved choristomatous malformation of the optic nerve and chiasm is presented. The patient experienced progressive unilateral vision loss and optic atrophy. A gadolinium-enhanced magnetic resonance image demonstrated chiasmal involvement that was not evident on computed tomographic scan or visual field testing. We believe this is the third reported case of a choristomatous malformation of the optic nerve and chiasm and the first report of magnetic resonance imaging findings.
