Fig. 6From: Mass-forming pancreatitis versus pancreatic ductal adenocarcinoma: CT and MR imaging for differentiationSoft tissue mass with vessel encasement in calcified CP: locally advanced PDAC (66 y, female). a Contrast-enhanced MDCT shows signs of severe CP with parenchymal calcifications (arrowheads) and a large intraductal stone (arrow) with duct dilatation. However, there is a non-calcified soft-tissue mass present, which infiltrates into the mesenteric root (thick arrow). b Coronal reformation shows encasement of the superior mesenteric artery by the mass (arrows), which is highly suspicious for PDAC. c Diagnosis was confirmed by percutaneous CT-guided transgastric biopsy (arrow)Back to article page
