Sclerosing Cavernous Hemangioma in the Cavernous Sinus: Case Report.

Cavernous hemangiomas of the cavernous sinus belong to a well-distinguished entity of extra-axial cavernous hemangiomas located in the cavernous sinus and have a typical appearance on magnetic resonance imaging (MRI). Severe intraoperative bleeding has been described during the excision of these lesions that is probably associated with their pathological features. An atypical case of a sclerosing lesion with distinct MRI features is described. In these particular cases, especially with giant hemangiomas where en bloc excision would be difficult, safe internal decompression and resection can be achieved.
