We present a 45-year-old man with chronic pancreatitis and the rare complication of large subcapsular splenic pseudocyst. He suffered from a slow growing left upper quadrant abdominal distension for 2 weeks and pain radiating to his back. On abdominal computed tomography, large subcapsular splenic pseudocyst (25×13×11 cm), multiple small sized pancreatic pseudocysts in the pancreas tail and chronic pancreatitis with multiple pancreatic stones were shown. He underwent percutaneous catheter drainage of the splenic pseudocyst and after 3 weeks, the size of the pseudocyst decreased. But, the pain radiating to his back and poor oral intake was not improved. Distal pancreatectomy, Roux-en-Y pancreaticojejunostomy, and splenectomy were performed and the patient was discharged after 2 weeks. A splenic subcapsular pseudocyst resulting from pancreatitis may be managed by percutaneous drainage, but according to a patient's clinical symptoms, operative management can be added.
