You may not experience any symptoms from pancreatic cysts, including pseudocysts. Pancreatic cysts are often found when imaging tests of the stomach area (abdomen) are done for another reason.
When signs or symptoms of pancreatic cysts do occur, they typically include:
- Persistent abdominal pain, which may radiate to your back
- A mass you can feel in your upper abdomen
- Nausea and vomiting
When to see a doctor
Cysts can become infected, though this is rare. See a doctor if you are feverish and have persistent abdominal pain.
A ruptured pseudocyst is a medical emergency. Fluid released by the pseudocyst can damage nearby blood vessels and cause massive bleeding. A ruptured pseudocyst can also cause infection of the abdominal cavity (peritonitis). Seek emergency medical treatment if you have signs or symptoms of internal bleeding and shock, including:
- Severe abdominal pain
- Decreased consciousness
- Weak and rapid heartbeat
- Vomiting of blood
