Pancreatic Cyst

The discovery of a pancreatic cyst can be concerning, but it's important to know that many of these growths are not cancerous. North Shore Gastroenterology provides patients with clear answers, state-of-the-art diagnostics, and a personalized plan to manage their health with confidence.

What are Pancreatic Cysts?

A pancreatic cyst is a fluid-filled sac that develops on or inside the pancreas. With the growing use of high-resolution imaging techniques like CT and MRI scans, these cysts are being detected more frequently, often as incidental findings during tests for unrelated medical conditions.

While most pancreatic cysts are benign and may never cause problems, some have the potential to become cancerous. Therefore, the most critical step after diagnosis is to accurately determine the type of cyst to assess its risk and create an appropriate management plan.

Types of Pancreatic Cysts

Pancreatic cysts are broadly categorized based on their potential to become cancerous.

These are typically benign and include pseudocysts, which often develop after a bout of pancreatitis. They are not true cysts but rather collections of fluid and do not have malignant potential.

These cysts have a very low risk of becoming cancerous and are typically monitored rather than treated.

This group requires careful evaluation due to its malignant potential. It includes intraductal papillary mucinous neoplasms (IPMNs) and mucinous cystic neoplasms (MCNs). Accurate identification and monitoring of these cysts are crucial for preventing pancreatic cancer.

Symptoms of Pancreatic Cysts

Most pancreatic cysts do not cause any symptoms, which is why they are often found by chance. When symptoms do occur, it is usually because the cyst has grown large enough to press on nearby organs or to block a duct in the pancreas.

Potential symptoms may include:

  • Persistent abdominal pain.
  • Nausea and vomiting.
  • A sense of fullness after eating very little.
  • Unexplained weight loss.
  • Jaundice: A yellowing of the skin and eyes.

Diagnosing Pancreatic Cysts

Distinguishing a harmless cyst from one that may require treatment is a complex process that demands specialized expertise.

An evaluation will help determine the nature of the cyst and may include the following steps:

A multiphase CT scan or MRI provides detailed images of the pancreas and cyst, allowing us to assess its size, location, and specific features.

This essential diagnostic procedure uses a specialized endoscope equipped with an ultrasound probe. The device is inserted through the mouth into the stomach and small intestine, providing detailed, close-up images of the pancreas.

During an EUS, a very thin needle can be passed through the endoscope and into the cyst to collect a sample of the fluid. The fluid is then sent to a lab to be analyzed for tumor markers and cellular changes that can help determine the type of cyst.

Treating Pancreatic Cysts

The management of a pancreatic cyst is highly individualized and depends on its type, size, features, and your overall health.

Treatment may include:

For small, low-risk cysts, the best approach is often careful observation. This typically involves periodic imaging (such as MRI or EUS) to monitor for any changes in size or characteristics over time.

Surgery may be recommended if a cyst has high-risk features, is causing symptoms, or is found to be cancerous. The type of surgery depends on the cyst's location within the pancreas.
