| Summary: | Hemorrhagic pseudocyst (HP) and pseudocyst-associated pseudoaneurysms (PPs) are complications of pseudocyst. Angiography with embolization has been advocated as the first-line intervention for HP. A 47-year-old man with groove pancreatitis combined with HP near the pancreatic head was treated conservatively. He had relapsed pancreatitis with a newly identified pseudoaneurysm; however, the pseudocyst size was reduced. Although pseudoaneurysm was identified, angiography was not performed because there was no evidence of ongoing bleeding, and he was in a stable condition. Sphincterotomy and stent insertion in the pancreatic duct was applied to prevent relapsed pancreatitis with facilitation of the flow of pancreatic juice. He has done well during the 10-month follow-up, without recurrent pancreatitis. Angiography as an initial approach in HP and PPs may need to be more selective depending on the clinical presentation of the patient. A lysed clot within the strictured pancreatic duct during the healing process has been thought to be the cause of relapsed pancreatitis, and pancreatic sphincterotomy and stent insertion should be the preferred treatment methods.
