Utility of pancreatography for diagnosing autoimmune pancreatitis

Figure 1 Pancreatography of autoimmune pancreatitis. A: Endoscopic retrograde cholangiopancreatography finding of autoimmune pancreatitis showing skipped lesions of the main pancreatic duct (short and long arrows); B: On magnetic resonance cholangiopancreatography, skipped lesions (short and long arrows) on endoscopic retrograde cholangiopancreatography were not visualized; C: Endoscopic retrograde cholangiopancreatography finding of autoimmune pancreatitis showing side branch derivation from the narrowed portion of the main pancreatic duct; D: Recent magnetic resonance cholangiopancreatography could show diffuse narrowing of the main pancreatic duct fairly well; E: Endoscopic retrograde cholangiopancreatography finding of autoimmune pancreatitis showing a short narrowed main pancreatic duct (arrow) with upstream dilatation less than 5 mm; F: On magnetic resonance cholangiopancreatography, the narrowed portion (arrow) was not visualized.
