A 52 year old man presented with a history of right groin pain. He also recollected at least three self limiting episodes of rigors, diarrhoea, and vomiting lasting for about four days in the recent past. Over the past year he had travelled worldwide with no reported medical illness. He was febrile and a pulsatile tender mass was felt in the right iliac fossa. Ultrasound scan revealed a common iliac aneurysm measuring 3.5 cm in diameter.
