Rheumatoid vasculitis, an extra-articular component of rheumatoid arthritis, causes a wide spectrum of manifestations that range from clinically insignificant to life-threatening disease. As a systemic necrotizing arteritis, rheumatoid vasculitis is usually characterized by end-organ ischemia. Herein we describe a patient with abdominal pain and syncope due to intra-abdominal hemorrhage from a ruptured aneurysm of the inferior pancreaticoduodenal artery in the setting of rheumatoid vasculitis. Although the intra-abdominal hemorrhage was the unusual manifestation of rheumatoid vasculitis in this patient, he had a history of prior extra-articular rheumatoid disease, including pulmonary fibrosis and Sjögren's syndrome with associated parotid lymphoproliferative disease. In patients with rheumatoid arthritis who have abdominal pain and an unexplained rapidly decreasing hemoglobin concentration, the diagnosis of intra-abdominal hemorrhage from a ruptured visceral aneurysm due to rheumatoid vasculitis should be considered, even in the absence of other indications of systemic vasculitis.
