Abstract:

Pancreatic cystic lesions have various etiologies, including pseudocyst (inflammatory cyst), retention cyst, congenital cyst, and neoplastic cyst (1). Recently, we experienced a case with a unique pancreatic cyst-like lesion causing recurrent acute pancreatitis. This patient had multiple cystic dilatations of branch pancreatic ducts surrounded by proliferation of smooth muscle tissue, with neither neoplastic nor inflammatory changes. To our knowledge, there are no previous reports of such a case.
