a pancreatic pseudocyst is a fluid-filled sac that is often near the pancreas.
the pancreas is an organ behind the stomach that produces enzymes needed to break down food. it also produces insulin.
a pseudocyst can form after inflammation of the pancreas (pancreatitis). it also can occur after injury to the pancreas or after a health problem.
these cysts often do not cause symptoms. if a pseudocyst bleeds or gets infected, symptoms may include belly pain, fever, or chills. other possible symptoms include nausea, vomiting, and a yellow colour in the eyes and skin (jaundice).
a pseudocyst may not be treated if it doesn't cause symptoms. if it bleeds or becomes infected, it may be drained using a needle or through surgery. some pancreatic cysts may need to be removed to make sure they are not cancer.
