Head of pancreas mass. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, signal intensity, size and enhancement.Several small rim-enhancing lesions are compatible with metastatic disease the largest being a segment 2/3 lesion measuring 1.7 x 1.3 cm (series 1203/43) lesion. Additional lesion in segment 5. Several posterior segment lesions are too small to definitively characterize but demonstrate mild T2-weighted hyperintensity and restricted diffusion. The vessels are patent.Severe extra and moderate intrahepatic biliary ductal dilatation with common duct measuring 1.8 cm. The duct abruptly transitions at the level of the pancreatic head mass.SPLEEN: The spleen is normal in size morphology and signal intensity.PANCREAS: Heterogeneous pancreatic head mass measuring approximately 3.8 x 3.2 cm (series 5/14). There is mild pancreatic parenchymal atrophy distally and main pancreatic ductal dilatation up to 4 mm which is displaced dorsally.The GDA is encased by tumor and is not clearly opacified distally. Otherwise the celiac trunk and its branch vessels are patent. The superior mesenteric artery is spared.The lesion abuts approximately 90 degrees of the superior mesenteric vein, however the portal vein confluence and splenic vein appears spared.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: Small peripancreatic and aortocaval lymph nodes, the largest measuring 1.0 x 0.7 cm (series 1201/82).BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Head of the pancreas mass with bilobar hepatic metastases and vascular involvement as described above.Severe extrahepatic and moderate intrahepatic biliary ductal dilatation.
