I have several pancreatic cysts, as I also have a history of neuroendocrine tumors in the duodenum, I was concerned.  I had an MRI and then followed up with a ultrasound endoscopy.  They did  not look problematic so I am relieved.  Another MRI will be done in a year or so for follow up.  If you want more info, John Hopkins' website offers lots of info on pancreatic cysts. Best wishes as you follow up on these pesky things.
