A case of superior mesenteric artery occlusion associated with idiopathic chronic cold agglutinin disease

Abstract

A 64-year-old man who had been given a diagnosis of idiopathic chronic cold agglutinin disease in a medical clinic suffered from Raynaud's phenomenon and acrocyanosis in winter. He was admitted to our hospital with unbearable abdominal pain. Blood tests showed liver dysfunction with jaundice and severe acidosis. Abdominal angiogram and contrast-enhanced CT revealed superior mesenteric artery occlusion. These findings suggest that thrombosis due to cold agglutinin disease could be the cause of superior mesenteric artery occlusion.
