Subarachnoid hemorrhage (Hunt and Hess grade V) in a 19-year-old male patient.
A, Cerebral angiogram of the left vertebral artery shows distal aneurysm of the left superior cerebellar artery.
B, Selective opacification of the left superior cerebellar artery shows small aneurysm with favorable neck:body ratio.
C, Control angiogram obtained immediately after treatment shows complete aneurysmal occlusion.
D, MR image obtained at 6 months shows residual flow in the central part of the aneurysm without neck opacification.
E, MR angiogram obtained at 6 months shows residual flow in the central part of the aneurysm without neck opacification.
F, Follow-up conventional angiogram obtained at 12 months shows unchanged residual flow.
G, Follow-up MR angiogram obtained at 36 months shows unchanged residual flow.

Incidental aneurysm revealed by MR image of a 16-year-old male patient who complained of headaches.
A, Cerebral angiogram of the right vertebral artery shows large dysplastic aneurysm located 2 cm distal to the origin of the posterior inferior cerebellar artery.
B, Contrast-enhanced axial view T1-weighted image shows a partially enhanced mass close to the right part of the medulla.
C, Nonsubstracted control angiogram obtained immediately after occlusion by coils of the posterior inferior cerebellar artery at its origin shows complete occlusion of both the aneurysm and the parent vessel.
D, Axial view T1-weighted image obtained at 6 months shows complete disappearance of mass effect.
E, Follow-up conventional angiogram obtained at 12 months reveals no aneurysm recurrence.
F, Follow-up MR angiogram obtained at 36 months reveals no aneurysm recurrence.
