[Postexercise duplex ultrasound to diagnose external iliac endofibrosis]

Arterial endofibrosis is a disease of recent discovery which concerns high-performance athletes, predominantly competitive cyclists. The preferential location is the external iliac artery. The symptoms are diverse (pain, edema, paresthesia), always linked to an effort. The diagnosis may be delayed due to atypical symptoms in athletes. Complementary tests are measure of the systolic pressure index after exercise, duplex ultrasound, CT angiography, MR angiography and arteriography. We report a case of endofibrosis where late diagnosis was established with postexercise duplex ultrasound, while CT angiography and arteriography failed to reveal characteristic abnormalities.
