Table 2 Breakdown of diagnostic imaging findings for chronic pancreatitis as determined by the revised Japanese Clinical Diagnostic Criteria for chronic pancreatitis (From Ref. [54])

From: Autoimmune pancreatitis can develop into chronic pancreatitis

Findings of definite chronic pancreatitis (n = 15)

Number

a. Stones in pancreatic ducts

9

b. Multiple or numerous calcifications distributed in the entire pancreas

13

c. Irregular dilatation of the MPD and irregular dilatation of pancreatic duct branches of variable intensity with scattered distribution throughout the entire pancreas on ERCP

2

d. Irregular dilatation of the MPD and branches proximal to complete or incomplete obstruction of the MPD (with pancreatic stones or protein plugs) on ERCP

2

Findings of probable chronic pancreatitis (n = 1)

 

b. Irregular dilatation of pancreatic duct branches of variable intensity with scattered distribution throughout the entire pancreas, irregular dilatation of the MPD alone, or protein plugs on ERCP

1

c. Irregular dilatation of the MPD throughout the entire pancreas plus pancreatic deformity with irregular contour on CT

0

  1. This study did not evaluate MRCP or US (EUS) findings, so the probable chronic pancreatitis findings of (a) and (d), which are judged by these modalities, were excluded.
