Classification

• Cerebral aneurysms are classified by size.

1. Small aneurysms have a diameter of less than 15mm.
2. Larger aneurysms include those classified as large (15 to 25mm)
3. Giant (25 to 50mm)
4. Super giant (over 50mm)

• Cerebral aneurysms are classified by shape.

1. Saccular aneurysms are those with a saccular outpouching and are the most common form of cerebral aneurysm. Berry aneurysms are saccular aneurysms with necks or stems resembling a berry.
2. Fusiform aneurysms are aneurysms without stems.
