Figure 7: (a) Postcoiling follow-up MRI done after 6 months showed T2W hypointensity in right ambient cistern region (a and b) and a focal chronic lacune in right thalamus (c). Susceptibility weighted sequence showed hypointensity in the same right ambient cistern (d and e) suggesting aneurysm has shrunken in size. TOF MRA (f-h) showed no filling of the aneurysm and distal parietoccipital branch (g arrow pointing toward trapped aneurysm segment); however, distal calcarine branch is well opacified
