Mycotic Aneurysm of the External Iliac ArteryA Triad of Clinical Signs Facilitating Early Diagnosis

JAMA. 1977;238(3):245-246. doi:10.1001/jama.1977.03280030051025

MYCOTIC aneurysms may complicate the course of patients with Salmonella bacteremia. Such aneurysms usually occur in the aorta, but may arise in the femoral and popliteal arteries, or infrequently in an iliac artery.1,2 The majority of mycotic aneurysms are associated with few localizing signs and rupture before a definitive diagnosis is established. By contrast, mycotic aneurysms of the external iliac artery may produce localizing signs that facilitate early recognition. The first reported case of this lesion2 was marked by arterial insufficiency, femoral neuropathy, and bacteremia. In the present case (the second reported to our knowledge), there is a similar triad of signs suggesting that such manifestations generally accompany this lesion.

Report of a Case  A 62-year-old woman was admitted to St Joseph's Hospital because of recurrent fever and right leg pain. Twenty-nine years earlier, a complete hysterectomy had been performed on the patient followed by radiation treatments for
