The patient was a 31-year-old Armenian-American woman, single and nulliparous. She was an avid amateur athlete, formerly successful in competitive long-distance running and road bicycling. She had a 2-year history of bilateral thigh claudication during strenuous athletic activity, now resolved on the left but persisting on the right. She stated that her pain and tightness were centered “over the sartorius,” initially only during competitive athletics but now even with leisurely biking and running. The pain reliably resolved after a few minutes of rest, and never involved the calves or buttocks. The pain and restriction of endurance were sufficient to force her to discontinue participation in competitions.
