Multifocal autoimmune pancreatitis: A retrospective study in a single tertiary center of 26 patients with a 20-year literature review

Figure 2 A 72-year-old man with multifocal autoimmune pancreatitis. A-D: Diffusionweighted imaging and axial fat-suppressed T1 weighted image showed three indistinct mass-like swelling (arrows) in the pancreatic head, body, and tail; E: The pancreatic head lesion (arrow) could not be clearly shown on dynamic contrast enhanced-computed tomography; F: Dynamic contrast enhanced-computed tomography could only show a merged lesion in the pancreatic body/tail (arrow); G-H: Positron emission tomography-computed tomography images showed three focal intense uptakes of fluorodeoxyglucose in the whole pancreas, which were not detectable on dynamic contrast enhanced-computed tomography. B, D, and F: The computed tomography and magnetic resonance images demonstrated relatively normal volume of pancreas (arrowheads) in the pancreatic neck.
