ABSTRACT
Pancreatic serous cystadenoma is usually a benign tumor and observation alone without surgery has been known as the reasonable treatment in most cases. However, surgical resection is necessary in cases of uncertain diagnosis or a symptomatic serous cystadenoma. Pancreatic duct stenosis with a proximal duct dilatation due to a mass effect by serous cystadenoma is rare and pancreatitis can be followed. A 50-year-old female, who had no past medical history except a small amount of alcohol drinking, experienced acute pancreatitis with pancreatic pseudocyst. After endoscopic treatment of pancreatic pseudocyst with pancreatic stent and cystogastrostomy, she underwent distal pancreatectomy because pancreatic serous cystadenoma was considered as the cause of pancreatitis and pseudocyst. After the surgery, the patient is followed up for one year without recurrence of acute pancreatitis.
