Isolated iliac artery aneurysm rupture presenting as left iliac fossa pain and diarrhoea: A case report

Isolated iliac aneurysm rupture is rare and difficult to diagnose, but needs to be actively considered and excluded. We document the case of a 71 year old female who presented with left iliac fossa pain and diarrhoea and was subsequently found to have a ruptured isolated iliac artery aneurysm. This case demonstrates the importance of urgent diagnostic CT in surgical patients, who present with features of abdominal pain and shock. The key to survival is early diagnosis, appropriate resuscitation and prompt definitive open or endovascular repair.
