Figure 1: (a and b) Oblique and lateral DSA images of right vertebral artery angiogram showing a 6 mm sized narrow neck aneurysm arising from proximal PICA just after its origin. (c and d) Post coiling DSA images showing complete occlusion with preserved fl ow in PICA. (e and f) Follow-up MRA images after 1 year show stable occlusion of the aneurysm with good fl ow in PICA (white arrow in "e") and completely occluded aneurysm (black arrow on "f") DSA: Digital subtraction angiography, PICA: Posterior inferior cerebellar artery, MRA: Magnetic resonance angiography
