Pancreatic incidentalomas: Investigation and management.

Area of Science:

• Gastroenterology
• Radiology
• Oncology

Background:

• Pancreatic incidentalomas (PIs) are increasingly detected due to advanced imaging.
• PIs can be isolated duct dilation or solid/cystic lesions, with cystic lesions found in up to 49% of the population.
• Effective PI management is crucial for early pancreatic cancer diagnosis and preventing overtreatment.

Purpose of the Study:

• To summarize challenges in pancreatic incidentaloma management.
• To provide pragmatic suggestions for PI diagnosis and follow-up.
• To differentiate PIs with malignant potential from benign lesions.

Main Methods:

• Dedicated pancreas protocol CT or MRI for accurate characterization.
• Assessment of main pancreatic duct size and lesion characteristics (solid vs. cystic).
• Categorization of cystic lesions into IPMNs, MCNs (potentially malignant), or SCNs (benign).

Main Results:

• Solid lesions require high suspicion for malignancy.
• Cystic lesions necessitate further classification based on imaging features.
• Management strategies depend on duct dilation extent and lesion type.

Conclusions:

• Accurate initial imaging is vital for PI management.
• Distinguishing between benign and potentially malignant PIs is critical.
• A structured approach to PI management improves patient outcomes.
