Abstract 104: Fusiform intracranial aneurysms wall enhancement correlates with mass effect and symptomatic presentation

Intracranial aneurysms can cause symptoms due to brain parenchyma compression. It is unclear why some aneurysms may cause symptoms due to mass effect. Hence, recognizing symptoms from mass effect caused by these aneurysms based on their location and angiographic features may help in the triage of aneurysms for treatment vs observation. Our goal is to investigate the relationship between fusiform aneurysms’ mass effect, aneurysm wall enhancement (AWE) distribution, and symptomatic presentation.
