A case report; rapid expansion of a pseudoaneurysm secondary to chronic pancreatitis

Formation of peripancreatic pseudoaneurysm is a well-known complication of the chronic pancreatitis. Wall of pseudoaneurysm is very fragile and prone to rupture, which can be fatal. Recently, transcatheter embolization of pseudoaneurysm has been used as the first line treatment with successful results. In most cases, embolization is performed early in the course, and temporal evolution is rarely documented. We report a case of pseudoaneurysm originating from the dorsal pancreatic artery, which developed secondary to chronic pancreatitis. The pseudoaneurysm rapidly enlarged in 8 days to 4cm. We successfully embolized the peudoaneurysm using micro-coil system.
