Fig 1. A, Conventional DSA of the right ICA. The finding is a large supraophthalmic aneurysm (arrowheads) and a second medially cavernous aneurysm (double arrow). D, DSA after coil occlusion of both aneurysms. B, C, E, and F, T2-weighted and T1-weighted contrast-enhanced images 4 days (B and C) and 9 days (E and F) after intervention. MR image at the fourth postinterventional day shows edema in both optic tracts and thickening and signal-intensity elevation in the right optic nerve and chiasm (double arrows in B). C, T1-weighted postcontrast image shows enhancement at the rim of the aneurysm and the chiasm. MR images 9 days postintervention (E and F) show that edema and swelling have regressed, as well as the enhancement.
