Currently, a widely accepted IFCA definition exclusively based on morphology is lacking. Type 2 Excludes. Fusiform aneurysms are ovoid and elongated, while saccular ones are circumscribed, and spherical. An essential feature of the intracranial fusiform aneurysms is the communication between both lumens (the true lumen and the pseudolumen) through a disrupted portion of the internal elastic lamina in most of the cases. Although many factors may contribute to their development, fusiform aneurysms are generally suspicious for a dissecting etiology that may or may not have an atherosclerotic component.

A saccular aneurysm is a blister that can possibly burst and lead to hemorrhaging. Monitoring with MRI or CT. An essential feature of the intracranial fusiform aneurysms is the communication between both lumens (the true lumen and the pseudolumen) through a disrupted portion of the internal elastic lamina in most of the cases. In false aneurysms, blood escapes between tunica layers and they separate. Intracranial nonsaccular aneurysms occur in both the vertebrobasilar and internal carotid artery circulations.
