[True isolated atherosclerotic aneurysm of the axillary artery]

The true atherosclerotic aneurysm of the axillary artery is a rare condition. It either presents as a pulsatile axillary mass or arterial emboli in the hand and fingers. We report the case of a 70-year-old man with a 5 cm aneurysm of the axillary artery presenting with embolic disease to the hand. Angiography is helpful and provides valuable preoperative anatomic details. Surgery remains the treatment of choice but endovascular treatment can also be considered.
