Intraductal papillary mucinous neoplasm

Intraductal papillary mucinous neoplasm is most common in men in their 7th decade. Clinical symptoms are similar to chronic pancreatitis. The main duct type is more likely to be malignant when compared to the branch duct type.

The imaging findings are

• Duct dilatation

• • Main duct or side branch
  • Diffuse or focal (cystic appearing)

• Pancreatic glandular atrophy
• Calcification
• Bulging duodenal papilla (diagnostic of IPMN on ERCP)
