The imaging findings in 2015. (a) CECT: Mural nodules were detected in the dilated MPD of the pancreatic body. (b) MRCP: The MPD in the pancreatic body was dilated to 30 mm, whereas the pancreatic cyst in the pancreatic head was the same size as in 2007. (c) MRI-DWI: Positive signals were detected in the pancreatic body (arrow) and tail (arrowhead). EUS: Mural nodules of 12 mm in height in the MPD of the pancreatic body (d), and a well-circumscribed, low echoic mass lesion of 15 mm in diameter was detected in the pancreatic tail (e). CECT: contrast enhanced computed tomography, MPD: main pancreatic duct, MRCP: magnetic resonance cholangiopancreatography, DWI: diffusion weight imaging, EUS: endoscopic ultra sonography
