Fusiform aneurysmal dilatation of the infrarenal abdominal aorta measures 5.4 cm (AP) x 5.6 cm (W) x 6.7 cm (CC). It is about 5.9 cm inferior to the right main renal artery. It extends inferiorly until before the bifurcation. Presence of thick intramural haematoma at the superior half of the aneurysm measures 3.1 cm in maximum thickness.
There is poor plane of demarcation with the small bowel (at dudeno-jejunal junction) with presence of air-pocket in the superior part of the aneurysm suggestive of aorto-enteric fistula.
Presence of extensive periaortic strandings with adjacent loculated collection suggestive of chronic contained leak.
No contrast extravasation to suggest active leak.
