EUS with a FNA is a possibility, however in the cases of pancreatic cysts, there is a moderate chance for a false negative and the accuracy is still being determined in studies.

Other diagnostic options include evaluate of the cyst fluid with tumor markers (eg, CEA, CA 19-9, and many others).

Unfortunately, the definitive diagnostic test to differentiate cysts is difficult.  Each modality has its limitations.  Another option would be a core biopsy or percutaneous FNA to get a better idea of the characteristics of the fluid.  

Followup with your personal physician is essential.
