What is a Paraclinoid ICA aneurysm?

What is a hypophyseal aneurysm?

Background: Superior hypophyseal artery (SHA) aneurysms form a unique subgroup of paraclinoid aneurysms having a propensity to grow to a large size in the suprasellar region resulting in compression of the optic nerve, chiasma, and/or tract.
