At exploration, this thick-walled abdominal aortic aneurysm was adherent to surrounding structures and had a glistening white surface. A diagnosis of inflammatory aneurysm was made.

A close up view of the inflammatory aneurysm is shown.
Comment:
The constellation of wall thickening, adherence to surrounding structures and dense glistening fibrotic capsule was termed inflammatory aneurysm by Walker et. al. in 1978. These features are found in about 5% of abdominal aortic aneurysms. There may be adherence to duodenum, ureters and inferior vena cava. The etiology of the excessive inflammatory reaction is unclear. Trauma, extravasation, urine leakage, and autoimmune mechanisms have been suggested. The retroperitoneal inflammatory fibrosis regresses after graft placement.
