Patient 5: subarachnoid hemorrhage (Hunt and Hess grade II) in a 73-year-old female patient.
A and B, Left vertebral artery angiogram (lateral and anteroposterior views) shows distal aneurysm of the left superior cerebellar artery.
C, Intra-aneurysmal contrast injection shows opacification of the aneurysm and the distal branch.
D and E, After intra-aneurysmal glue injection left vertebral angiogram (lateral and anteroposterior views) shows complete obliteration of the aneurysm.

Patient 17: 23-year-old male patient with visual disturbances.
A and B, Left vertebral lateral and anteroposterior angiogram shows a distal aneurysm of the right PCA.
C, Selective opacification of the aneurysm and the distal branch.
D and E, After intra-aneurysmal injection of glue, left vertebral artery angiogram (lateral and AP view) shows complete occlusion of the aneurysm.
F, Lateral angiogram of the right ICA shows retrograde filling of the part of the PCA distal to the occluded aneurysm.

Patient 18: 49-year-old male patient with cranial nerve III nerve palsy.
A and B, Left vertebral oblique views before and after coil embolization.
C, Noncontrast CT scan 2 months after embolization shows a left occipital and left thalamic infarct.
