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.
非创伤性瘤周动脉瘤被认为是由于供血动脉的高血流需求和高血管病变的新生血管形成引起的，最常见于血管畸形，但也很少与肿瘤有关。这些瘤周动脉瘤中的大多数来自与颈内动脉分支相关的颅内血管。我们报告了一个独特的病例，即在术前血管造影中发现与巨大凸面脑膜瘤相关的脑膜中动脉动脉瘤。
