Pancreatic cysts are saclike pockets of fluid on or in your pancreas. The pancreas is a large organ behind the stomach that produces hormones and enzymes that help digest food. Pancreatic cysts are typically found during imaging testing for another problem.
The main categories of pancreatic cysts can be divided into two groups, nonneoplastic or neoplastic cysts. Each group includes many different subtypes of cysts, such as pseudocysts, serous cystadenomas and mucinous cystic neoplasms. Most aren’t cancerous, and many don’t cause symptoms. But some pancreatic cysts can be or can become cancerous.
- The cause of most pancreatic cysts is unknown. Some cysts are associated with rare illnesses, including polycystic kidney disease or von Hippel-Lindau disease, a genetic disorder that can affect the pancreas and other organs.
- Pseudocysts often follow a bout of a painful condition in which digestive enzymes become prematurely active and irritate the pancreas (pancreatitis). Pseudocysts can also result from injury to the abdomen, such as from a car accident.
- When signs or symptoms of pancreatic cysts do occur, they typically include:
- Persistent abdominal pain, which may radiate to your back
- Nausea and vomiting
- Weight loss
- Feeling full soon after you start eating
