What Are Pancreatic Cysts?
Pancreatic cysts are fluid-filled sacs that develop within the pancreas. Some cysts are benign and cause no symptoms, while others may become precancerous or cancerous over time. Common types include pseudocysts, serous cystadenomas, mucinous cystic neoplasms, and intraductal papillary mucinous neoplasms (IPMNs). Symptoms, if present, may include abdominal pain, nausea, bloating, or unintended weight loss. Diagnosis is typically made through imaging studies like CT, MRI, or endoscopic ultrasound (EUS). Treatment ranges from observation to drainage or surgical removal, depending on the cyst type, size, and potential cancer risk.
Common Causes and Risk Factors
History of pancreatitis (acute or chronic)
Genetic syndromes such as cystic fibrosis or familial pancreatitis
Smoking and heavy alcohol use
Age over 50 years
Family history of pancreatic disorders
Signs and Symptoms
Often none in early stages
Abdominal discomfort or a feeling of fullness
Bloating, gas, or indigestion
Unexplained weight loss
Mild fever if the cyst becomes infected
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Exam
He reviews your epigastric discomfort, fullness, digestive symptoms, past pancreatitis or genetic risk, plus alcohol and tobacco use.
Blood Tests
We measure pancreatic enzymes (amylase, lipase), liver function tests, inflammatory markers and tumor markers (e.g., CA 19-9).
Imaging Studies
Abdominal ultrasound screens for cystic lesions and assesses pancreatic structure.
Contrast CT scan or MRI/MRCP evaluates cyst size, complexity and relationship to ducts.
Endoscopic ultrasound (EUS) provides high-resolution images and guides fluid sampling when needed.
Fluid Analysis (if needed)
Under EUS guidance, fine-needle aspiration of cyst fluid is sent for cytology, CEA, amylase and molecular markers to gauge malignancy risk.

Frequently Asked Questions
What causes pancreatic cysts?
Most pancreatic cysts develop after an episode of pancreatitis, but genetic syndromes, advancing age, smoking and heavy alcohol use can also increase your risk.
What types of pancreatic cysts are common?
The most common are serous cystadenomas, mucinous cystic neoplasms and intraductal papillary mucinous neoplasms (IPMNs).
Do pancreatic cysts go away on their own?
Some small cysts may remain stable or even shrink over time. Dr. Scott monitors them with regular imaging to track any changes.
When should I worry about a pancreatic cyst?
Contact us if you experience new or worsening abdominal pain, unexplained weight loss, fever or if your cyst shows rapid growth on scans.
How often will I need follow-up scans?
Imaging follow-up is typically scheduled every 3-12 months, depending on your cyst's type, size and risk factors.
Can lifestyle changes help manage pancreatic cysts?
Yes. A low-fat diet, avoiding alcohol and tobacco, staying hydrated and maintaining a healthy weight can help ease symptoms and slow growth.
