Gliomatosis cerebri - A rare cause of bilateral blindness

Abstract

We describe a rare case of gliomatosis cerebri (GC) with bilateral blindness. A 45-year-male presented with gradual painless loss of vision both eyes (BE), with generalised tonic–clonic seizures. On examination, the patient denied light perception BE, with sluggishly reacting pupil. Fundus examination revealed papilledema and absent foveal reflex. Magnetic resonance imaging showed features of diffuse infiltrating glial tumor suggesting GC. Visual impairment can occur rarely due to optic nerve involvement, however bilateral cases has not been reported. Early recognition of GC may allow preservation of vision through focal radiotherapy to the optic nerve.
