Apoplexy in Optochiasmatic Cavernous Hemangioma Causing Visual Diminution: A Case Report

Cavernous hemangioma of the optic chiasm is extremely rare, representing 1% or less of all cavernous hemangioma.1 Klein et al described the earliest reported lesion in 1979.2 Patients typically present with chiasmal apoplexy, characterized by sudden visual disturbance, headache, retro-orbital pain, and nausea.3 Acute dysfunction of the chiasm and/or optic nerve has been called chiasmatic apoplexy3 and/or optic nerve apoplexy.4 Both are rare events.5 Authors report here a rare patient who presented with optic chiasm apoplexy caused by a cavernous hemangioma of the optic chiasm.
