FIG 3. Middle cerebral artery aneurysm with high-signal-intensity rim artifact and recurrence 6 months after treatment with detachable coils.

A, Axial fast spin-echo T2-weighted MR image (3394/80) shows a 2-mm rim of increased signal intensity around the coils (arrow).

B, Axial nonenhanced MOTSA 3D TOF MRA source image demonstrates recurrence of the aneurysm (arrow).

C, Nonenhanced MOTSA 3D TOF MRA image shows recurrence (arrow).

D, Contrast-enhanced MOTSA 3D TOF MRA image shows the same recurrence (arrow).

E, DSA image obtained 6 months after treatment confirms the presence of recurrence (arrow).
