How many types of pancreatic cysts are there?
There are two major types of pancreatic cysts; pseudocysts (inflammatory cysts) and true cysts (non-inflammatory cysts). Inflammatory cysts are benign, whereas non-inflammatory cysts can be benign, precancerous, or cancerous.
What is the most common pancreatic cyst?
The most common type is called intraductal papillary mucinous neoplasm (IPMN). These cysts connect with the pancreatic duct, and their fluid usually has a large amount of digestive pancreatic enzymes. The cysts can occur in both men and women and are more common in people older than 50 years.
What percentage of pancreatic cysts are cancerous?
Most cysts are not – less than 1-2 percent of pancreatic cysts are cancerous. However, some may be considered precancerous.
Are small cysts on pancreas common?
Pseudocysts develop as a complication of inflammation of the pancreas (pancreatitis). This type of cysts is frequently surrounded by fibrous tissue and may be lined with scar tissue or inflammatory tissue. About 75% to 80% of pancreatic cysts are pseudocysts, and they affect about 1 in every 1,000 adults per year.
Do pancreatic cysts grow quickly?
In the majority of patients, asymptomatic small incidental pancreatic cysts remained stable during a median follow-up period of 2.2 years; however, in 27% of patients, cysts increased in size over time, with 11% growing after an initial 1-year period of stability.
How fast do pancreatic cysts grow?
For cysts that increased in size, the median growth rate was 2.3 mm per year ( IQR , 1.5–4.4 mm/year), with a median overall increase of 4.8 mm ( IQR , 3.4–7.9 mm) in the largest dimension during the study period.
Do pancreatic cysts need to be removed?
Some types of pancreatic cysts require surgical removal because of the risk of cancer. Surgery might be needed to remove an enlarged pseudocyst or a serous cystadenoma that’s causing pain or other symptoms. A pseudocyst may recur if you have ongoing pancreatitis.

How are pancreatic pseudocysts differentiated from true cysts?
Pancreatic pseudocysts are different from true pancreatic cysts. Both cysts and pseudocysts are collections of fluid. A true cyst is a closed structure . It has a lining of cells that separates it from the nearby tissue. A pseudocyst isn’t closed and doesn’t have a lining of epithelial cells separating it from the nearby tissue.
What are the symptoms of a cyst in the pancreas?
Pancreatic cysts and pseudocysts are growths in the pancreas. Symptoms, if present, include nausea, abdominal bloating, and pain. Cysts and pseudocysts should be treated to avoid complications such as rupture or infection.
What is the prognosis of pancreatic pseudocysts?
