Abstract:
Nontraumatic perilesional aneurysms are thought to occur because of high-flow demands of feeding arteries and neoangiogenesis of hypervascular lesions, most commonly in vascular malformations, but they can rarely be associated with tumors as well. Most of these perilesional aneurysms are from intracranial vasculature associated with branches off the internal carotid artery. We report the unique case of a middle meningeal artery aneurysm associated with a giant convexity meningioma seen on a preoperative angiogram.
