Pancreatic cysts are fluid-filled sacs that can develop within the pancreas, an organ located behind the stomach. These cysts can be either benign or potentially precancerous. 


Pancreatic cysts are relatively common and are often discovered incidentally during imaging tests conducted for unrelated health concerns. 


These cysts can be either benign or potentially precancerous. Precancerous cysts often contain mucin and can be either mucinous cystic neoplasms (MCNs) or intraductal papillary mucinous neoplasms (IPMNs). 


These often need long-term surveillance depending on their imaging characteristics and can require surgery, especially if they have the potential to develop into pancreatic cancer.

Causes and Risk Factors

The exact cause of pancreatic cysts is not always clear, but certain risk factors may contribute to their development. These risk factors include:

  • Chronic pancreatitis
  • Family history of pancreatic cancer or cysts
  • Certain genetic syndromes, such as von Hippel-Lindau syndrome and polycystic kidney disease



Pancreatic cysts typically do not cause any symptoms, especially if they are small and non-cancerous. However, in some cases, larger cysts or those associated with complications may lead to the following symptoms:

  • Abdominal pain or discomfort
  • Nausea and vomiting
  • Bloating
  • Appetite changes
  • Jaundice, in cases where the cysts affect the bile duct
  • Recurrent attacks of pancreatitis



The diagnosis of pancreatic cysts usually involves imaging tests, such as CT scans, MRIs, and endoscopic ultrasounds, to visualize the pancreas and identify any abnormalities. These tests help determine the size, location, and characteristics of the cysts. The most important step in the diagnostic process is to exclude a cancer or precancerous cyst. In some cases, a biopsy may be recommended to analyse the cyst fluid and assess the risk of cancer.



Treatment for pancreatic cysts depends on the specific type of cyst, its size, and the potential risk of malignancy. Treatment options may include:

  • Observation and regular monitoring with imaging tests for asymptomatic and low-risk cysts
  • Drainage or surgical removal of the cyst, especially for symptomatic or high-risk cysts
  • Management of complications, such as infection or obstruction, through appropriate interventions and medications


Regular follow-up visits with a healthcare provider are essential for individuals diagnosed with pancreatic cysts to ensure proper monitoring and timely intervention, if necessary. Close surveillance is crucial to detect any changes in the cysts and to prevent the progression to pancreatic cancer.
