Fig 5. A 66-year-old man presenting with seizures with an unruptured left middle cerebral artery aneurysm. A, Precoiling angiogram. B, Complete occlusion after coiling. C, Stable complete occlusion at 6 months. D, MRA at 6.6 years shows a 6 x 4 mm recurrence (arrow). E, Angiogram before the second coiling. F, After the second coiling, again complete occlusion is seen. G, Six months after the second coiling, repeat reopening of the aneurysm is noted. H, After the third coiling, again complete occlusion is seen. Note that the coil mesh is much larger than the aneurysmal lumen in A. I, Initial CT angiography before the first coiling demonstrates thrombus surrounding the aneurysm lumen and perifocal edema. J, MR imaging at 6.6 years shows migration of the coil mesh in the thrombosed part of aneurysm and a perianeurysmal cyst.
