FIG 1. Case 1: 39-year-old man.
A, Right vertebral injection, lateral view, shows aneurysm located at the telovelotonsillar segment (cranial loop) bifurcation of the PICA in its hemispheric and vermian branches.
B, Intraaneurysmal contrast injection, lateral view, shows opacification of the aneurysm and progressive filling of the hemispheric branch.
C, Postembolization right vertebral injection, anteroposterior view, shows occlusion of the aneurysm with a small remnant at the level of the neck.
D, 7-month follow-up right vertebral injection, anteroposterior view, shows complete occlusion of the aneurysm, with no visible neck remnant. The distal PICA appears normal.

FIG 2. Case 2: 38-year-old woman.
A, Right vertebral injection, lateral view, shows aneurysm located at the telovelotonsillar segment bifurcation of the PICA, in its hemispheric and vermian branches.
B, Postembolization right vertebral injection, lateral view, shows complete occlusion of the aneurysm with normal-appearing distal PICA.

FIG 3. Case 3: 44-year-old woman.
A, Left vertebral injection, lateral view, shows distal aneurysm in the hemispheric branch of the right SCA.
B, Intraaneurysmal contrast injection, lateral view, shows opacification of the aneurysm. Note absence of an aneurysmal neck and filling of the distal branch.
C, Postembolization left vertebral injection, lateral view, shows occlusion of the aneurysm and parent artery. Proximal SCA segment is not opacified owing to spasm caused by withdrawal of the microcatheter.
