Figure 3.

An 80-year-old woman with a right internal artery aneurysm. A) Computed tomography angiography (CTA) demonstrated a 35 × 35-mm aneurysm with a thick mural thrombus in the main trunk of the internal iliac artery just proximal to the superior gluteal artery (arrowhead). B-C) Digital subtraction angiography (DSA) just before and after coil embolisation showed complete occlusion of the aneurysm. D) On time-resolved magnetic resonance angiography there was no apparent enhancement in the aneurysm. A tiny, high-intensity area (asterisk) indicated a venous flow artefact because it was continuously observed before an injection of gadolinium chelate. E) CTA showed a tiny contrast-enhanced area in the caudal part of the aneurysm (arrow). F) On DSA recanalisation was not detected
