A 36-year-old woman with a history of erythema nodosum, left-eye uveitis, and bilateral episcleritis experienced flulike symptoms for 3 years, including generalized fatigue and soreness in her shoulders, hips, and back. She also developed episodes of effort-induced left arm pain and weakness and episodes of visual “whiteouts” whenever exposed to bright light. Examination showed her blood pressure to be 140/90 mm Hg on the right arm and unobtainable on the left arm. The left radial pulse was not palpable. There was a
harsh right-sided cervical bruit. She was seen by numerous physicians without a conclusive diagnosis. She was noted to be anemic, and further investigations were undertaken to evaluate her gastrointestinal tract.
