Get StartedSymptoms
By Mayo Clinic staffYou may have pancreatic cysts, including pseudocysts, but experience no symptoms. When signs or symptoms do occur, they typically include:
- Persistent abdominal pain, which may radiate to your back
- A mass you can feel in your upper abdomen, where your pancreas is located
- Nausea and vomiting
When to see a doctor
Cysts can become infected, so see a doctor if you are feverish and have persistent abdominal pain.
A ruptured pseudocyst is a medical emergency. Fluid in the cyst contains enzymes activated for digestion. When a cyst ruptures, the released fluid can damage nearby blood vessels and cause massive bleeding. Seek emergency medical treatment if you have signs or symptoms of internal bleeding and shock, including:
- Fainting
- Severe abdominal pain
- Decreased consciousness
- Rapid heartbeat
