Lower abdominal pain (mimicking diverticulitis) and isolated groin/hip pain are relatively common presentations of AAA and iliac artery aneurysm and rupture. As many as 15-20% of symptomatic AAAs wil present with hip and/or groin pain.
Bottom line: AAA and iliac artery aneurysm should at the very least be considered in older patients (and in patients with vascular disease) who present with unexplained groin/hip pain.
