[Periarteritis nodosa complicated by intrapancreatic vascular rupture].
Clinical pancreatic manifestations are unusual in polyarteritis nodosa. A case of intrapancreatic hemorrhage due to vascular rupture occurring during the course of histologically proven polyarteritis nodosa is described. The patient presented with massive hemoperitoneum requiring emergency laparotomy. Splenopancreatectomy was performed to control bleeding. Steroid therapy was continued during the postoperative course, with favorable outcome. The mechanism of vascular rupture is not clear, but is probably related to focal arteritis with consequent infarction. No ruptured microaneurysm was found in this case.
