 Cysts of the pancreas are caused by various underlying diseases. From the viewpoint of clinical practice, it is required for us to differentiate the cysts by neoplastic tumors from the other ones. When diagnosing cystic lesions of the pancreas, we have to recall characteristic findings, including those provided by diagnostic imagings, of neoplastic cysts as well as of solid tumors associated with retention cysts or with intratumoral cysts resulting from liquefied necroses.

 There may be a number of acute inflammatory cysts of the pancreas which disappear spontaneously. Treatment modalities for these pancreatic cysts include an interventional method as well as surgery. Based on the results of treatment in 36 patients, we suggest therapeutic guidelines for the pancreatic cysts as follows; 1) conservative regimen may be allowed in expecting spontaneous resolution when the cysts are smaller than 5 cm in diameter, 2) interventional treatment such as percutaneous puncture aspiration or drainage is indicated for those larger than 5 cm in diameter because of high risk of complications and also for those which do not decrease in size in 4 weeks after a conservative regimen is applied. With these nonsurgical treatments, improvement was observed in approximately 3/4 of our patients with acute inflammatory cysts. In the paper, we emphasize the contribution of modern diagnostic imagings to the diagnosis and treatment of pancreatic cysts.
