  • Title: Isolated celiac artery aneurysm with splenic artery stenosis as a rare presentation of polyarteritis nodosum: a case report and review of the literature.
    Author: Adajar MA, Painter T, Woloson S, Memark V.
    Journal: J Vasc Surg; 2006 Sep; 44(3):647-50. PubMed ID: 16950448.
    Abstract:
    Polyarteritis nodosum (PAN) is a vasculitic disease that affects small to medium arteries. It often presents as a systemic and multiorgan disease that affects the skin, joints, gastrointestinal tract, kidneys, and nervous system. Nonspecific signs and symptoms are the hallmarks of PAN. It rarely affects single vessels, although there have been case reports of PAN involving single intra-abdominal vessels. The authors present a case of a 42-year-old white man who presented with mild epigastric pain but was otherwise asymptomatic. The workup ultimately revealed a rare case of an isolated celiac artery aneurysm with a concomitant stenosis of the splenic artery secondary to PAN. The patient was treated with high-dose steroid therapy, with resultant resolution of the vasculitis and a decreased size of the aneurysm.
