Cavernous hemangioma of the optic nerve. Case report.

A case of cavernous hemangioma of the optic nerve of a 24-year-old pregnant woman is reported. The visual disturbance with subacute onset was thought to be related to the delivery of a child. The lesion was totally removed through the subfrontal approach, resulting in satisfactory recovery of visual symptoms. Cavernous hemangioma involving the optic nerve and chiasm is extremely rare. Only two similar cases have been reported previously.
