Abstract
Cerebral pseudoaneurysms are focal dilatations of an artery that involve all three layers of the vessel wall, unlike true aneurysms. They typically arise after trauma, iatrogenic (ventricular drain insertion, transsphenoidal surgery, etc.), or infections. Common presentations include headache, subarachnoid hemorrhage, or focal neurological deficits depending on the location and size of the pseudoaneurysm. Diagnosis often involves imaging techniques such as computed tomography angiography (CTA) or magnetic resonance angiography (MRA). Treatment options vary depending on the size, location, and clinical presentation and may include conservative observation, endovascular embolization, or surgical intervention.
