Figures
- Fig 1.
A, T1-weighted MR image. B, T2-weighted MR image. Note the intramural thrombus (arrow) and intimal flap (arrowhead). C, Left VA injection (3D reconstruction) shows a fusiform aneurysm of the left VA-PICA. D, After endovascular treatment, a control angiogram of the right VA injection demonstrates that the left PICA is well filled and the aneurysm is completely occluded.

Images obtained in a 59-year-old man who presented with SAH due to a ruptured right VA-PICA aneurysm. A, CT scan. B, 3D reconstruction of the right VA injection. The patient had undergone right VA coil occlusion, after which he recovered. C, Left VA angiogram after right VA occlusion reveals that the right PICA is filled via the left VA and the aneurysm is decreased in size.
