Pancreatic Cysts: What to Do When One Is Found

Pancreatic cysts are fluid-filled sacs in or on the pancreas. They are increasingly found by chance on CT or MRI scans done for other reasons, and they become more common with age. Most never cause problems, but some types can slowly become cancerous, so they need the right follow-up.

Types

• Pseudocysts: collections of fluid after pancreatitis, not true tumors
• Serous cystadenomas: almost always benign
• Mucinous cysts (IPMN and MCN): can turn into cancer over time and need monitoring

Follow-up

How closely a cyst is watched depends on its size, type, and features:

• MRI/MRCP at regular intervals for most small cysts
• Endoscopic ultrasound (EUS) for cysts that are larger, growing, or have concerning features. EUS gives a close-up view and can sample the cyst fluid with a thin needle.
• Surgery for cysts at high risk of becoming cancerous

Warning signs

• Jaundice (yellow skin or eyes)
• New diabetes
• Weight loss or ongoing belly or back pain
• A cyst that grows quickly or develops a solid part
