Abstract

Polyarteritis nodosa (PAN) is a systemic vasculitis affecting mainly small and medium sized arteries. Over 50% of the cases, PAN may cause gastrointestinal symptoms. Main gastrointestinal symptoms are abdominal pain, vomiting, nausea, diarrhea and melena. A very rare case of isolated PAN affecting the jejunum, manifested as stricture, is reported. A 55-year-old woman with prior history of hypertension presented herself complaining of abdominal pain and weight loss. Radiologic studies showed a segmental narrowing of the jejunum. At the time of surgery, 3cm length narrowed, thickened fibrotic intestinal wall was found at 110cm distal to the Treitz ligament. Pathological finding showed acute necrotizing vasculitis of a medium sized artery.
