Core Tip
Core tip: Incidental pancreatic cysts have been found in far more patients with the improvement of cross-sectional imaging tests. Many of these lesions have malignant potential, especially the mucinous lesions, and imaging alone is not enough to guarantee definitive diagnosis. Cyst fluid carcinoembryonic antigen (CEA) has been used as the most important cyst fluid marker to distinguish mucinous from nonmucinous cysts. More recently, glucose has emerged as a useful cyst fluid marker for the identification of pancreatic mucinous cysts with an accuracy similar to or even better than CEA.
