![]() ![]() Case Descriptions: In the first case: A large right temporal meningioma with erosion of the sphenoid greater wing and extension toward infratemporal fossa and right orbit ‑ a large pseudoaneurysm of right middle cerebral artery branch was found end embolized during DSA. Here, we report on two challenging cases of giant meningiomas associated to vascular malformations and we discuss the pertinent literature. ![]() ![]() Nonetheless, the coexistence of meningiomas with vascular malformations has previously been reported and it has been evidenced that this event could be underestimated because of neglect of preoperative DSA. Preoperative DSA is mainly performed to obtain embolization of the lesion, although a number of complications have been reported after this procedure. Background: The role of preoperative digital subtraction angiography (DSA) in meningiomas is currently under discussion because of the introduction of noninvasive magnetic resonance imaging (MRI) angiography to study vascular anatomy associated to the tumor. ![]()
