Hemorrhagic Cavernous Sinus Hemangioma with Sudden-Onset Abducens Palsy.

BACKGROUND: We report a rare case of hemorrhagic cavernous sinus hemangioma with sudden onset of abducens palsy.

CASE DESCRIPTIONS: Sudden onset of diplopia occurred in a 49-year-old female. Head computed tomography findings revealed a high-density mass in the right cavernous sinus with protrusion to the sphenoid sinus. Endoscopic endonasal surgery was performed, though early recurrence was noted. A Gamma Knife surgical procedure was then performed to prevent early recurrence after histopathologic confirmation of cavernous sinus hemangioma. Thereafter, the tumor was controlled and abducens palsy disappeared.

CONCLUSIONS: For treatment of cavernous sinus hemangioma, stereotactic radiosurgery should be considered as primary or adjuvant treatment in the very early phase after removal, to avoid early recurrence.
