Pancreatic cysts are fluid-filled sacs that form in the pancreas, an organ located behind the stomach. These cysts can vary in size and may be discovered incidentally during imaging tests for other conditions. While many pancreatic cysts are benign and do not cause symptoms, some can lead to complications or indicate the presence of more serious conditions. Most pancreatic cysts are classified as either serous cystadenomas or mucinous cystic neoplasms. Diagnosis typically involves imaging techniques like ultrasound or CT scans. Treatment options depend on the type and symptoms, ranging from monitoring to surgical removal if necessary.
