Pancreatic Cysts
Overview
Pancreatic cysts are growths filled with mucus, pus or other materials that can develop inside the pancreas, which is a comma-shaped gland about six inches long that sits behind the stomach near the first part of the small intestine (A.K.A the duodenum).
The pancreas has two main functions that are very crucial to health: making insulin, which helps the body regulate blood sugar, and making digestive juices called enzymes that help the body break down and digest food in the intestines.
While most pancreatic cysts occur for no discernible reason, some develop as a result of pancreatitis, which is a long term (“chronic”) or short-term (“acute”) inflammation of the pancreas characterized by sometimes severe or prolonged abdominal pain and fibrosis, in which the pancreas is damaged by the buildup of scar tissue. Read more about pancreatitis.
Pancreatic cysts can cause no symptoms, and most people don’t even know they have them. Many pancreatic cysts are discovered accidentally during a CT scan or MRI scan of the abdomen during treatment for an unrelated condition.
Types, Symptoms & Causes of Pancreatic Cysts
There are over a dozen different kinds of pancreatic cysts. Most pancreatic cysts are benign, meaning they aren’t cancerous and won’t become cancerous. Certain types of benign pancreatic cysts, however, can potentially develop into cancer. Some of the more common types of pancreatic cysts include:
Intraductal Mucinous Neoplasms (IPMN) – The most common type of benign pancreatic cysts that have a potential to become cancerous are Intraductal Papillary Mucinous Neoplasms (IPMN). This type of cyst develops in the ducts inside the pancreas that transport fluids from the pancreas to the intestine and are usually filled with thick mucus containing digestive pancreatic enzymes. IPMN cysts occur in both men and women but are more common in those over 50 years old.
Pancreatic Pseudocysts – Usually caused by pancreatitis, which is a short- or long-term inflammation of the pancreatic tissue, pancreatic pseudocysts are collections of digestive enzymes that can leak from the pancreas because the organ is inflamed. Unlike a true pancreatic cyst, a pseudocyst isn’t closed, and doesn’t have a lining that separates it from other tissues.
Mucinous Cystic Neoplasms – While Mucinous Cystic Neoplasms are less common than IPMN, this type of pancreatic cyst can also potentially become cancerous. Mucinous Cystic Neoplasms are usually diagnosed in middle-aged women, and are usually located in parts of the pancreas known as the “body” and “tail”
Solid Pseudopapillary Neoplasm – A rare form of pancreatic cyst that has fluid, cyst-like filling combined with some solid components. Found mostly in younger women, solid pseudopapillary neoplasms also have the potential to become cancerous.
Serous Cystadenoma – Serous cystadenoma are most commonly found in women over 50 years old. They have a very low risk of developing into cancer.

Symptoms & Causes of Pancreatic Cysts
Because pancreatic cysts often display no signs or symptoms, many people don’t know they have pancreatic cysts until they are discovered during imaging tests for unrelated issues in their abdomen.
Rarely, some pancreatic cysts do cause symptoms. These may include:
- Abdominal pain that may be recurring, persistent or severe, and which may radiate to your back
- Unexplained nausea and vomiting
- Unexplained weight loss
- Jaundice, which is yellowing of the eyes and skin
- A swelling or lump in the abdomen that can be felt through the skin
- Feeling very full even though you’ve just started eating
In some cases, pancreatic cysts and pseudocysts can become infected or even rupture. Symptoms of infected or ruptured pancreatic cysts or pseudocysts can include:
- Fever
- Peritonitis, which is a serious infection of the abdominal cavity
- Vomiting blood
- Feeling confused
- Pain in the abdomen that can be severe
- A rapid or weak heartbeat
- Internal bleeding
- Going into shock
Risk Factors
There are a number of factors that are thought to potentially increase your risk of developing pancreatic cysts. These include:
- Having a history of acute or chronic pancreatitis, which is inflammation of the pancreas. Read more about pancreatitis care at Hoag.
- Smoking
- Having gallstones, which are pebble-like deposits that can form inside the gallbladder. Read more about gallstones.
- Binge drinking or alcohol abuse, which can contribute to pancreatitis, which is a leading cause of pancreatic cysts.
Diagnosis & Tests for Pancreatic Cysts
Most pancreatic cysts cause no pain or other noticeable symptoms. Because of this, most pancreatic cysts are found by accident, during CT or MRI scans of the abdomen for unrelated medical issues.
If one or more cysts is discovered in your pancreas, your doctor will classify them as “high risk” or “low risk” for being cancerous. Features that can suggest a cyst with a higher risk of being cancerous include:
- If the patient has noticeable symptoms
- Swollen lymph nodes (AKA lymphadenopathy)
- If the patient’s main pancreatic duct has a diameter greater than 5 millimeters
- A cyst with thickened walls
- A solid component within the cyst
- A cyst bigger than 3 millimeters
Based on these observations, your doctor may recommend surveillance — which is evaluating the cyst over time to see if it’s changing or growing.
However, some pancreatic cysts that have multiple issues that suggest they could be cancerous may require diagnosis through what’s called Endoscopic Ultrasound-Guided Fine-Needle Aspiration (EUS/FNA).
EUS/FNA is a technique that uses the images created by endoscopic ultrasound to precisely guide a needle passed through the skin while collecting tissue and cyst fluid samples. These samples can then be studied in a lab for the presence of cancer or components that may suggest the cyst may be more likely to become cancerous.
Allowing for pinpoint-accurate biopsy of suspected tumors or lesions inside the body, EUS/FNA gives physicians the ability to more easily detect serious conditions, early-stage cancers and other diseases. Read more about EUS/FNA and other advanced diagnostic techniques at Hoag.
Next-Generation Imaging of Abdominal Conditions at Hoag
At the Hoag Digestive Health Institute, we’re committed to using the most advanced diagnostic techniques available to provide you and your family a diagnosis you can depend on. Why? Because more accurate diagnosis leads to a more personalized treatment plan, and that can have a big difference on recovery and outcomes. At Hoag, imaging tests we use to diagnose issues of the pancreas, liver, bile ducts and other organs may include:
- Abdominal Ultrasound, which uses sound waves to create images of structures and tissues inside the body, including gallstones or obstructions of the bile ducts that might be causing blockages, inflammation or cholangitis.
- Endoscopic Retrograde Cholangiopancreatography (ERCP), in which doctors use X-rays, a radioactive tracer substance and a small, flexible camera called an endoscope to view the bile ducts and examine them for tumors, gallstones or narrowing. During the ERCP procedure, physicians pass an endoscope down your throat, through the stomach, into the small intestine and into the bile ducts.
- Hepatobiliary Iminodiacetic Acid (HIDA) Scan (A.K.A. Cholescintigraphy) which utilizes a harmless radioactive tracer that’s injected into your bloodstream to “light up” the bile ducts on imaging scans. This allows the bile ducts and any obstructions in them to be more easily seen by physicians
- Magnetic Resonance Cholangiopancreatography (MRCP), which utilizes powerful magnetic fields, radio waves and advanced computing to evaluate the gallbladder and bile ducts without the use of ionizing radiation
Management, Surveillance & Treatment for Pancreatic Cysts
Pancreatic Cyst Surveillance Program
Hoag’s pancreatic cyst surveillance program follows a set of guidelines and protocols for monitoring and managing pancreatic cysts. It involves regular imaging tests and follow-up appointments with a healthcare provider to monitor the size, appearance, and characteristics of the cyst over time.
The goal of a pancreatic cyst surveillance program is to identify any changes in the cyst that may indicate an increased risk of developing into pancreatic cancer. This allows for early detection and treatment, which can improve outcomes and increase the chances of a successful recovery.
Learn more about Hoag’s Pancreatic Cyst Surveillance Program.
Symptomatic Pancreatic Cysts
If the cyst shows signs of growth or changes in appearance, your healthcare provider may recommend additional testing or treatment options, such as biopsy or surgery. Regular surveillance is crucial for ensuring the best possible outcome for patients with pancreatic cysts.
If pancreatic cysts are causing symptoms or if they are at a high risk for becoming cancerous, the preferred treatment is surgical removal of the cysts.
For most cysts that aren’t producing symptoms and have little to no risk of becoming cancerous, however, your doctor may recommend leaving the cyst in place and observing it over time.
Advanced Surgery for Pancreatic Conditions at Hoag
The vast majority of pancreatic cysts won’t become cancerous. But for the small percentage that do and other serious pancreatic conditions, Hoag is ready to help you fight.
Hoag is Orange County’s highest-volume cancer treatment center, and a national leader in next-generation surgery for pancreatic cancer, advanced robotic-assisted surgeries and minimally-invasive procedures. At Hoag, surgical options for pancreatic cancer may include:
- The Whipple Operation, which usually involves surgical removal of part of the pancreas, bile duct, gallbladder duodenum and occasionally a portion of the stomach. This surgery is not only used to treat pancreatic cancer but may also be used to treat disorders that may lead to pancreatic cancer, like pancreatitis and benign tumors of the pancreas.
- Central Pancreatectomy, a highly specialized procedure that removes tumors on the “neck” of the pancreas, preserving other pancreatic tissues.
- Laparoscopic/Robotic-Assisted Pancreatectomy, which is a minimally-invasive procedure in which advanced robots assist in the removal of a large portion of the pancreas through small openings in the body.
- Duodenum Preserving Pancreatic Head Resection, usually recommended for patients with chronic pancreatitis, this surgery removes the “head” of the pancreas while preserving the duodenum and bile duct. Hoag is one of the few hospitals in the U.S. to offer this groundbreaking approach.
- Enucleation of pancreatic islet cell tumors, in which islet cell tumors — usually found on the surface of the pancreas — are carefully excised while preserving healthy pancreatic tissue. Hoag’s pancreatic surgical team has developed innovative, minimally-invasive techniques to complete this procedure, for less post-surgical pain and faster recovery.

Prevention of Pancreatic Cysts
Researchers can’t yet explain why some people develop pancreatic cysts while others of similar age, lifestyle, diet, etc. do not.
One of the best ways to reduce your risk of pancreatic cysts is to reduce your risk of pancreatitis, which is a major reason pancreatic cysts develop. Potential ways to reduce your risk of pancreatitis include:
- Avoid developing gallstones — small, pebble-like deposits in the gallbladder which are the most common reason for acute pancreatitis — by eating a healthy, balanced diet and avoiding fatty or high-cholesterol foods. Read more about gallstone treatment at Hoag.
- Maintain a healthy weight by eating a nutritious diet and getting regular exercise.
- Limit your intake of alcohol, especially if you’ve previously had acute pancreatitis related to binge drinking or alcoholism.
- Get regular checkups, including blood work that can suggest changes in pancreatic function.
Pancreatic Cyst Surveillance Program at Hoag
The specific components of Hoag's pancreatic cyst surveillance program may vary depending on the type and characteristics of the cyst, as well as other individual factors such as age and overall health. However, it typically involves regular imaging tests such as MRI, CT scans, or endoscopic ultrasound, as well as consultations with a gastroenterologist or other healthcare provider.
The definition of low or medium risk for pancreatic cysts depends on several factors, including the type and characteristics of the cyst, as well as individual patient factors such as age and overall health.
In general, non-mucinous cysts such as simple cysts, serous cystadenomas, and pseudocysts are considered low-risk, while mucinous cysts such as mucinous cystic neoplasms and intraductal papillary mucinous neoplasms are considered medium to high-risk.
Other factors that may be considered when assessing the risk of a pancreatic cyst include its size, location, and appearance on imaging studies. For example, larger cysts are generally considered to have a higher risk of developing into cancer than smaller cysts.
Surveillance is often chosen over surgery for pancreatic cysts because it avoids the risks and impact of surgery, especially for cysts with a low risk of cancer. Surveillance involves regular monitoring to detect changes, and it’s tailored to the patient’s health and preferences. Surgery is considered when there’s a higher risk or concerning changes in the cyst.
The frequency of check-ins with your doctor for pancreatic cyst surveillance depends on several factors, including the type of cyst, its size, and any changes observed during previous monitoring. Typically, check-ins may occur at intervals such as:
-
Every 6 months: For low-risk cysts that have remained stable over time.
-
Every 3-6 months: For medium-risk cysts, especially if there have been subtle changes or concerning features observed.
-
More frequently: In cases where there’s rapid cyst growth, new symptoms, or other worrisome developments.
-
Less frequently: For very low-risk cysts that have shown no changes during previous check-ins, your doctor may extend the intervals between appointments.
It’s crucial to follow the specific surveillance plan recommended by your healthcare provider. They will tailor the schedule based on your individual circumstances and the characteristics of the cyst. Regular check-ins allow for early detection of any concerning changes and ensure timely intervention if needed. Always communicate any new symptoms or concerns to your doctor between scheduled visits.
If there are changes in the size or shape of a pancreatic cyst during surveillance, it’s important to follow up promptly with your healthcare provider. These changes may indicate a higher risk or the need for further evaluation and intervention. Here’s what typically happens if changes are observed:
-
More Frequent Monitoring: Your doctor may recommend more frequent imaging, such as MRI or CT scans, to closely track the changes in the cyst’s size and shape.
-
Additional Testing: In some cases, additional tests like endoscopic ultrasound (EUS) or fine-needle aspiration (FNA) may be ordered to assess the cyst more thoroughly and obtain samples for analysis.
-
Consultation: You may be referred to a specialist, such as a gastroenterologist or pancreatologist, for a more in-depth evaluation and to discuss potential treatment options.
-
Treatment Consideration: Depending on the changes observed and the risk level of the cyst, treatment options may be discussed. This could include surgical removal of the cyst or other procedures to manage or reduce the risk of cancer development.
-
Shared Decision-Making: Your healthcare team will work with you to make informed decisions about the next steps, taking into account your individual health and preferences.
It’s crucial not to ignore any changes in the size or shape of a pancreatic cyst during surveillance, as early detection and intervention can significantly improve outcomes if the cyst is found to be at an increased risk of cancer. Regular communication with your healthcare provider and adherence to the recommended surveillance schedule are essential for effective management.
It’s important to note that the classification of a cyst as high-risk does not automatically necessitate surgery but may lead to more aggressive monitoring or further diagnostic tests to confirm the risk level accurately. Treatment decisions for high-risk cysts are typically made on a case-by-case basis, taking into account the patient’s overall health and preferences. The goal is to balance the potential benefits of early intervention with the risks associated with surgery.
High-risk pancreatic cysts are typically defined based on several factors and characteristics that collectively increase the likelihood of the cyst developing into cancer. While specific criteria can vary among healthcare providers and guidelines, here are some common features that may classify a cyst as high-risk:
-
Mucinous Cyst Type: Cysts that are confirmed to be mucinous, such as mucinous cystic neoplasms (MCNs) or intraductal papillary mucinous neoplasms (IPMNs), are often considered higher risk due to their association with malignancy.
-
Size: Larger cysts, especially those greater than 3 cm (about 1.2 inches) in diameter, are often considered high-risk because they have a greater potential for cancerous changes.
-
Changes Over Time: Rapid growth or significant changes in the cyst’s size or characteristics observed during surveillance can raise concerns about malignancy.
-
Solid Components: The presence of solid components within the cyst, as seen on imaging studies, is often associated with a higher risk of malignancy.
-
Location: Cysts located in certain parts of the pancreas, such as the main pancreatic duct, may be considered high-risk due to their proximity to critical structures.
-
Patient Symptoms: New or worsening symptoms, such as abdominal pain or jaundice, may raise concerns about the cyst’s potential for malignancy.
-
Family History: A family history of pancreatic cancer or pancreatic cysts may increase the perceived risk of a cyst.
-
Cytology and Biomarkers: Analysis of fluid obtained from the cyst during fine-needle aspiration (FNA) or other procedures may reveal concerning cellular or molecular features that suggest a higher risk.
-
Multidisciplinary Assessment: A team of healthcare professionals, including gastroenterologists, radiologists, and surgeons, may collectively assess the cyst’s risk based on a combination of clinical, radiological, and pathological findings.
Surveillance may be preferred over immediate surgery for high-risk pancreatic cysts for several reasons:
-
Risk-Benefit Assessment: The decision to pursue surgery is not taken lightly. It involves weighing the potential benefits of surgery against the risks and potential complications. In some cases, the risks associated with surgery may outweigh the benefits, especially if the cyst is small, asymptomatic, or the patient has significant underlying health issues.
-
Surgical Risks: Pancreatic surgery is a major procedure and carries inherent risks, including infection, bleeding, damage to surrounding structures, and a lengthy recovery period. These risks can be particularly significant in older individuals or those with pre-existing health conditions.
-
Quality of Life: Surgery can have a substantial impact on a patient’s quality of life. It may lead to digestive problems, hormonal imbalances, and the need for long-term medications and dietary modifications.
-
Incomplete Removal: In some cases, surgical removal of a cyst may not be curative, especially if there is concern that cancer cells have already spread beyond the cyst. Surgery may not eliminate the risk entirely, and the cancer may still recur.
-
Advancements in Surveillance: Surveillance techniques and technology have advanced, allowing for more precise and less invasive monitoring of high-risk cysts. Frequent imaging and close observation can detect changes early, enabling timely intervention if needed.
-
Shared Decision-Making: The decision to pursue surgery or surveillance should be a shared one between the patient and their healthcare team. Patients’ preferences, values, and overall health play a crucial role in determining the best approach.
-
Continuous Monitoring: Surveillance allows for continuous monitoring of the cyst’s behavior and characteristics. If there are concerning changes or signs of progression during surveillance, surgery can still be considered at a later stage.
-
Multidisciplinary Assessment: High-risk pancreatic cysts are typically evaluated by a team of specialists who collaborate to determine the most appropriate course of action. This ensures a comprehensive and tailored approach to care.
In summary, surveillance is considered a valid approach for high-risk pancreatic cysts because it allows for close monitoring while minimizing the immediate risks and impact associated with surgery. However, it’s important to emphasize that the decision to opt for surveillance over surgery should be based on careful evaluation, individual patient factors, and ongoing communication between the patient and their healthcare team. If significant changes are observed during surveillance or if the cyst becomes more concerning, surgery may be reconsidered as a treatment option.
For individuals with high-risk pancreatic cysts, the frequency of check-ins with a doctor is typically more frequent compared to those with lower-risk cysts. The exact schedule for check-ins can vary based on the specific characteristics of the cyst and the recommendations of your healthcare provider. However, it often involves:
-
Every 3-6 Months: High-risk cysts usually require closer monitoring, which often means check-ins with your healthcare provider every 3 to 6 months.
-
Imaging: During these check-ins, you may undergo imaging tests such as MRI or CT scans to closely monitor the cyst’s size, appearance, and any changes.
-
Clinical Evaluation: Your healthcare provider will also conduct a clinical evaluation, which includes discussing any symptoms or changes in your health.
-
Consultation with Specialists: High-risk cysts may require consultation with specialists, such as gastroenterologists or pancreatologists, to ensure comprehensive management.
-
Additional Testing: Depending on the findings during check-ins, additional testing or procedures (e.g., endoscopic ultrasound, fine-needle aspiration) may be recommended to assess the cyst more thoroughly.
-
Shared Decision-Making: Your healthcare team will work with you to make informed decisions about the ongoing management of the high-risk cyst, including the potential need for surgery or other interventions.
It’s essential to adhere to the recommended schedule for check-ins and promptly report any new symptoms or changes in your condition to your healthcare provider. High-risk cysts require vigilant monitoring to detect any concerning developments early and to facilitate timely intervention if necessary.
If there are changes in the size or shape of a high-risk pancreatic cyst during surveillance, it is a matter of significant concern, and further evaluation and potential intervention may be necessary. Here’s what typically happens if changes are observed in a high-risk pancreatic cyst:
-
Increased Surveillance Frequency: Your healthcare provider will likely recommend more frequent monitoring through imaging tests (such as MRI or CT scans) to closely track the changes in the cyst’s size and shape. This allows for early detection of any concerning developments.
-

-
Consultation with Specialists: Changes in a high-risk cyst may prompt a referral to specialists, such as gastroenterologists or pancreatologists, who have expertise in managing pancreatic diseases.
-
Additional Testing: Depending on the nature of the changes observed and the level of concern, additional tests or procedures may be recommended to assess the cyst more thoroughly. This could include endoscopic ultrasound (EUS), fine-needle aspiration (FNA) for sampling, or other diagnostic procedures.
-
Treatment Consideration: If the changes indicate a higher likelihood of malignancy or progression to cancer, treatment options such as surgery or other interventions may be discussed as part of the management plan.
-
Shared Decision-Making: The treatment decisions will be made collaboratively between you and your healthcare team, taking into account your individual health, preferences, and the specific characteristics of the cyst.
