FIG 4. Anterior communicating artery aneurysm with recurrence 8 months after treatment with coils.

A, DSA image shows large anterior communicating artery aneurysm.

B, DSA image shows complete occlusion after coiling.

C, Axial nonenhanced MOTSA 3D TOF MRA source image obtained 8 months after treatment demonstrates recurrence (arrow).

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

E, DSA image obtained 8 months after treatment confirms the presence of recurrence due to coil compaction (arrow).
