Figure 36. Chronic calcified pancreatitis. (A) Plain radiograph of the pancreatic area shows multiple calcified stones. (B) ERCP with the catheter placed in the ventral pancreatic duct shows that stones are partially broken (arrowhead) after extracorporeal shockwave lithotripsy. Stones are located in the Santorini duct. (C, D) MRCP in the axial (C) and coronal (D) planes clearly demonstrates the exact location of the filling defects (arrows) in the Santorini duct and the marked ductal alterations of chronic pancreatitis (enlargement of the main duct, irregularities, and side branch dilatation). This case illustrates the potential of MRCP as a guide for endoscopic therapy and for follow-up studies.
