An aneurysm is an abnormal bulge or “bubble” that forms in the wall of a blood vessel. When it occurs in the brain, it is known as a cerebral or intracranial aneurysm. Aneurysms can develop in different sizes and shapes, ranging from small and unruptured to large and potentially life-threatening.
The exact cause of aneurysms is not always clear, but certain risk factors can contribute to their formation, including:
In many cases, cerebral aneurysms do not cause symptoms until they rupture. Unruptured aneurysms are often found incidentally during diagnostic imaging studies performed for other reasons.
Symptoms of a ruptured cerebral aneurysm can vary but commonly include:
Ruptured cerebral aneurysms are considered medical emergencies that require immediate medical attention.
Diagnosis of cerebral aneurysms usually involves imaging studies, such as magnetic resonance angiography (MRA) or computed tomography angiography (CTA), which can visualize the blood vessels in the brain and detect the presence and characteristics of an aneurysm.
The management of cerebral aneurysms depends on several factors, including the size, location, shape, and overall health of the patient. Treatment options may include:
The choice of treatment depends on various factors, including the aneurysm’s size, location, and shape, as well as the patient’s overall health and preferences. The goal of treatment is to prevent rupture and manage the risk of complications.
It’s important to note that the management and prognosis of cerebral aneurysms can vary widely depending on individual factors. Regular follow-up care and close monitoring are essential for individuals with known cerebral aneurysms or those who have undergone treatment to ensure early detection of any changes or complications.
