3. Figure 2
ERCP showing a dilated pancreatic duct with multiple intraductal stones. Prior to referral to Mayo, patient (no. 1) was diagnosed with chronic pancreatitis and treated with stenting of pancreatic duct stricture and extracorporeal shockwave lithotripsy for dissolution of stones.

(A and B) Calcification in peripherally located small ducts. (B) There is also duct wall calcification. Note that there is no IPMN associated with the calcification.

(A) Intraluminal and (B) duct wall calcification. (A) Squamous metaplasia is seen in adjacent duct. Pancreatic ducts shown were located remotely from the region of pancreas involved by IPMN.
