Hi and welcome to HCM,thank you for your query.
at this point it doesnt require any treatment since there is no growth or obstruction of main pancreatic duct
. Also,there is no risk of malignancy.So if you dont have symptoms you dont have to be worried since this is just benign pancreatic cyst
which is common accidental finding. All you need is frequent follow up.
Wish you good health. Regards.
