Abstract:
Autoimmune pancreatitis (AIP) is a new category of pancreatic diseases. AIP associated with pseudocysts is rare; only 8 cases have been reported in the literature. A 63-year-old man was admitted to our department because of upper left abdominal pain and back pain. Various imaging studies demonstrated swelling of the tail of the pancreas with hemorrhagic pseudocysts. The patient underwent a surgical operation. A pancreatogram of the specimen revealed total occlusion of the main pancreatic duct in the tail of the pancreas. Histopathological examination revealed that it was AIP with hemorrhagic pseudocysts.
