Incidental pancreatic cysts are being increasingly recognized recently with incremented concern about health and frequent health check-up. Endoscopic ultrasound (EUS) has emerged as the principal modality for imaging pancreas for various pancreatic diseases including pancreatic cyst. But imaging alone cannot accurately identify the exact nature of the pancreatic cyst. EUS-guided fine needle aspiration is a useful adjunctive procedure to differentiate pancreatic cystic lesions. Cystic fluid analysis with cytologic evaluation is important to diagnose etiology of pancreatic cystic lesions, helping the clinician to more accurately assess the presence or potential for malignancy.
