Hemorrhagic Cavernous Sinus Hemangioma with Sudden-Onset Abducens Palsy

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

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.

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.
