Pseudoaneurysm of the dorsalis pedis artery is an uncommon condition that is usually caused by a traumatic injury or an iatrogenic intervention. The patient usually complains of an enlarging painless, pulsatile mass. A tentative diagnosis may be made by palpation of the pulsatile mass and detection of an associated systolic bruit. Color Doppler sonographic and arteriographic examinations can be used to confirm the diagnosis. We report the case of a 17-year-old patient with a posttraumatic pseudoaneurysm of the dorsalis pedis artery. Sonographic examinations revealed pulsatile flow into and out of a cystic structure surrounded by a thick hypoechoic wall and a "to-and-fro" pattern in the neck of the vascular mass; these findings were consistent with the diagnosis of a pseudoaneurysm. Angiography confirmed the diagnosis. The patient was treated with ligation of the artery and resection of the pseudoaneurysm. He recovered well after surgery and remained free of symptoms 3 months postoperatively. We believe that color Doppler sonography should be the procedure of choice for use in diagnosing pseudoaneurysms; arteriography can then be used to evaluate the alternative blood supply before surgery is undertaken.
