Extra-axial cavernous sinus hemangiomas are rare and account for less than 1% of parasellar tumors. These lesions have characteristic radiological features but the differential diagnosis from parasellar meningiomas and schwannomas can be difficult. Preoperative diagnosis is important due to the risk of severe intraoperative bleeding and the complex neurovascular structures of the cavernous sinus. We describe two cases of cavernous sinus hemangiomas and review the imaging findings of these lesions.
