Figures
- Fig 1.
AP (A) and lateral (B) right ICA angiograms show a 9-mm superior hypophyseal aneurysm and a 4-mm ventral paraclinoid ICA aneurysm before coil embolization.
- Fig 2.
AP (A) and lateral (B) right ICA angiograms obtained immediately after coil embolization of the larger superior hypophyseal aneurysm. The smaller, ventral paraclinoid ICA aneurysm remains unchanged.
- Fig 3.
AP (A), lateral (B), and 3D rotational (C) right ICA angiograms at 10 weeks display complete regression of the previously visualized ventral paraclinoid ICA aneurysm.
- Fig 4.
AP (A), lateral (B), and 3D rotational (C) right ICA angiograms at 10 months display a stable coil configuration within the superior hypophyseal artery aneurysm and continued absence of the ventral paraclinoid ICA aneurysm.
