Fig. 10From: Mass-forming pancreatitis versus pancreatic ductal adenocarcinoma: CT and MR imaging for differentiationCalcific CP of the pancreatic head (70 y, male): biliary and pancreatic stents in situ. a Axial MDCT shows 2 stents in place (large arrows), which impairs assessment of the pancreatic head. No real mass is seen, but the fat around the superior mesenteric artery (SMA) is blurred (small arrows). b Coronal MDCT reformation confirms infiltration of the perivascular fat around the SMA (small arrows). Histopathology revealed PDAC. Calcifications are seen in the pancreatic head (arrowhead). Dense residual contrast is present in the duodenum and stomach after ERCP: delayed emptying is due to stenosis of the duodenum in CPBack to article page
