An aneurysm is a bulge or ballooning in the wall of a blood vessel, often described as a weakened area that expands. While many aneurysms can exist without symptoms, a ruptured aneurysm can cause severe symptoms such as a sudden, excruciating headache (often described as the “worst headache of my life”), nausea, vomiting, a stiff neck, blurred or double vision, and light sensitivity. Aneurysms can be detected using MRI, particularly with a specialized technique called magnetic resonance angiography (MRA). MRA provides detailed images of blood vessels, allowing doctors to identify the size, shape, and location of an aneurysm.
