Multimedia
 | Media file 1: Sonogram through the left hypochondrium shows a large septate mass anterior to the kidney (K). (See Images 2-3 in Multimedia.) |
 | Media file 2: Nonenhanced axial CT scans in the same patient as in Image 1 shows a large septate mass in the left hypochondrium. Note the smooth external contour typical of a mucinous cystic neoplasm (MCN). (See Images 1 and 3 in Multimedia.) |
 | Media file 3: Enhanced axial CT scans in the same patient as in Image 2 shows a large septate mass in the left hypochondrium with rim enhancement and enhancement of the septa. At surgery, a mucinous adenoma was confirmed. Note the smooth external contour typical of MCN. (See Images 1-2 in Multimedia.) |
 | Media file 4: Contrast-enhanced axial CT scans through the tail of the pancreas show a large enhancing tumor occupying the left hypochondrium with both cystic and solid components. (See Image 5 in Multimedia.) |
 | Media file 5: Superior mesenteric angiograms in the same patient as in Image 4 in Multimedia show a hypervascular tumor. The tumor also derives its blood supply from the celiac axis (not shown). At surgery, a mucinous carcinoma of the pancreatic tail was confirmed. |
 | Media file 6: Axial and sagittal sonograms through the pancreas show a 1.93-cm cystic mass in the head of the pancreas. (See Image 7 in Multimedia.) |
 | Media file 7: Nonenhanced (left) and contrast-enhanced axial CT scans through the pancreas in the same patient as in Image 6 in Multimedia. These scans confirm the presence of a cystic mass in the anterior part of the head of the pancreas. The contrast-enhanced image shows a septum within the mass. |
 | Media file 8: T2-weighted (top) and short-tau inversion recovery (STIR) (bottom) MRIs through the pancreas in the same patient as in Images 6-7 in Multimedia. MRIs show a hyperintense lesion in the head of the pancreas. |
 | Media file 9: Magnetic resonance cholangiopancreatogram (MRCP) in the same patient as in Images 6-8 in Multimedia shows the cystic mass in the region of the head of the pancreas. At surgery, a mucinous adenoma was confirmed. |
 | Media file 10: Pancreatic intraductal papillary mucinous tumor (IPMT). Contrast-enhanced axial CT scans through the pancreas show a 5.5-cm cystic tumor in the pancreatic head. Note the upstream, gross dilatation of the pancreatic duct. The accessory pancreatic duct is also dilated. |
 | Media file 11: Pancreatic intraductal papillary mucinous tumor (IPMT). (Top) Superior mesenteric angiogram in the same patient as in Image 10 shows capillary vascularity in the mass in the pancreatic head mass during the arterial phase. (Bottom) The portal venous phase image shows displacement of the portal venous branches and encasement of the junction of the superior mesenteric vein and the portal vein. M denotes the pancreatic mass. |
 | Media file 12: Pancreatic intraductal papillary mucinous tumor (IPMT). Contrast-enhanced axial CT scans through the pancreas show a multiseptate tumor in the head of the pancreas. |
 | Media file 13: Pancreatic intraductal papillary mucinous tumor (IPMT). Contrast-enhanced CT scans through the pancreas show gross dilatation of the pancreatic duct. At surgery, IPMT was confirmed. |
 | Media file 14: Pancreatic microcystic adenoma. Plain radiograph shows tumor calcification in a microcystic adenoma (left upper quadrant). Calcification in the microcystic adenoma presents as a central cluster arranged in a sunburst or stellate arrangement. Central calcification is better evaluated with CT than with radiography. (See Image 16 in Multimedia.) |
 | Media file 15: Pancreatic microcystic adenoma. Sonogram in the same patient as in Image 14 in Multimedia shows a cystic mass in the region of the tail of the pancreas. |
 | Media file 16: Pancreatic microcystic adenoma. Contrast-enhanced axial CT scans in the same patient as in Images 14-15 shows a hypervascular tumor in the pancreatic tail with sunburst calcification. Note the Swiss-cheese enhancement. |
 | Media file 17: ERCP typically shows a patulous ampulla of Vater with discharging mucus, which is often diagnostic for IPMT. |
