Cavernous sinus hemangioma treatment
Surgical resection is the mainstay of treatment for hemangioma, reducing the likelihood of disease recurrence dramatically. When located in the cavernous sinus, however, the decision to perform complete surgical resection has to be carefully weighed against the risks of neurovascular injury, where up to 40% of tumors exhibit severe intraoperative bleeding 1), resulting in high intraoperative mortality, up to 12.5% in the literature 2) (although this is probably in large part due to reporting bias).
