The Circle of Willis is a vital part of the brain’s blood supply system. It is a circular network of arteries located at the base of the brain. Lesions in this area can lead to serious health problems, including strokes. Understanding the types, causes, symptoms, diagnostic tests, treatments, and preventive measures for Circle of Willis lesions is crucial for early detection and management.
Types of Circle of Willis Lesions
- Aneurysms: Bulging of a blood vessel wall.
