Traumatic occlusion of the external iliac artery in a racing cyclist: a cause of ill defined leg pain.

Stenosis of the external iliac artery in healthy athletes, although uncommon, has been reported in competition cyclists. A case of a racing cyclist whose chronic vague leg symptoms were incorrectly attributed to L4/5 nerve root irritation is reported. This highlights the importance of clinical vascular testing when assessing ill defined leg pain. The role of trauma as a causative factor in this condition has not been previously documented.
