Intracranial hypertension and papilledema secondary to an unruptured arteriovenous malformation: Review of the literature.

Arteriovenous malformations (AVMs) are abnormal connections of arteries and veins without intermediate capillary components. As such, AVMs can remain asymptomatic or have a variety of clinical presentations ranging from mild headaches to severe symptoms like seizures, hemorrhage, and subsequent coma. Papilledema and increased intracranial pressure without hydrocephalus or hemorrhage are rare forms of presentations of cerebral AVM.

Traumatic middle meningeal artery aneurysm: a case report.

Introduction: Traumatic intracranial aneurysms are rare, making up about 1% of all intracranial aneurysms. They can happen due to direct injury or blunt force, with the middle cerebral artery being the most frequent site. The middle meningeal artery (MMA) is the main artery that supplies the cranial dura mater, and, because of its location, is susceptible to damage after trauma.
