Abdominal computed tomography scan demonstrated a voluminous right common iliac aneurysm adjacent to the lumen of the sigmoid. Angiography (fig 3
) confirmed this, and laparotomy showed a large aneurysm from the right common iliac artery fistulised in the sigmoid which was embedded in the pelvis. A femoral-femoral bypass grafting procedure for revascularising the right limb was completed, the thrombosed aneurysm removed, and a left colectomy without primary anastomosis was performed. Histological examination of the colectomy specimen confirmed the fistula. The patient was discharged to her local hospital on day 30.
