Figure 4 Focal autoimmune pancreatitis with calcification after spontaneous remission in case 4. A, B, and C: The pancreatic head is enlarged with progressive enhancement, the wall of the common bile duct is thickened and abnormally enhanced (arrow); D: Magnetic resonance cholangiopancreatography (MRCP) showed a longer stenotic segment of the pancreatic duct (arrow) and bile duct, and dilatation of the upstream pancreatic duct (arrow) and proximal bile duct; E: Computed tomography follow-up after 12 mo showing that the swelling of the pancreatic head has dissipated, and multiple punctate calcifications (arrow) occur; F: The diseased pancreatic duct and bile ducts have nearly returned to normal on MRCP follow-up.
