Pseudoaneurysm represents a rare complication in chronic pancreatitis, caused by enzymatic digestion of peripancreatic arteries or the erosion of a visceral artery by pseudocysts. The presence of multiple pseudoaneurysms is rarely seen and their association with splenic infarction has been rarely reported. This case presentation reports the concomitant presence of two pseudoaneurysms with different mechanisms of formation, one of them diagnosed by EUS features and histology of pseudotumoral chronic pancreatitis; the second was diagnosed by contrast-enhanced transabdominal US and CT scan. Their association with splenic infarction was explained by ischemic pathogenesis.
