A cyst is a closed sac, having a distinct membrane and division on the nearby tissue. It may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst could go away on its own or may have to be removed through surgery.
PANCREAS
The pancreas is an organ approximately six inches long that is located in the abdomen behind the stomach. The pancreas is divided into three regions; the head, the body, and the tail. The head of the pancreas is located in the right abdomen adjacent to the duodenum, the tail is in the left abdomen, and the body lies between the head and the tail.
PANCREATIC CYST
Pancreatic cysts are collections (pools) of fluid within the head, body, or tail of the pancreas. Some pancreatic cysts are true cysts, that is, they are lined by a special layer of cells that are responsible for secreting fluid into the cysts. Other cysts are pseudocysts and do not contain specialized lining cells. Pancreatic cysts can range from several millimeters to several centimeters in size.
Symptoms of pancreatic cyst
The symptoms of pancreatic cysts depend on their size and location. Small (less than two cm) cysts usually cause no symptoms. Large pancreatic cysts can cause abdominal pain and back pain presumably by putting pressure on surrounding tissues and nerves. Large cysts in the head of the pancreas also may cause jaundice (yellowing of the skin and eyes with darkening of urine color) due to obstruction of the common duct. Obstruction causes bile to back up and forces bilirubin (the chemical that produces jaundice) back into the bloodstream.
On rare occasions, acute pancreatitis can cause the formation of large pseudocysts that can compress the stomach or the duodenum leading to obstruction to flow within the intestines, abdominal pain and vomiting. These cysts also may become infected and lead to fever, chills, and sepsis.
