Known 2.5 cm pancreatic head neuroendocrine tumor. ABDOMEN: LIVER, BILIARY TRACT: The liver is normal in size and morphology. There are numerous bilobar cysts. No suspicious liver lesion. The vessels are patent. The common bile duct measures up to 6 mm and tapers smoothly distally without a filling defect.SPLEEN: No significant abnormality noted.PANCREAS: There is significant main pancreatic ductal dilatation up to 8 mm with an abrupt transition at the level of the pancreatic head. There is moderate distal pancreatic parenchymal atrophy. At the transition point there is a faint region of restricted diffusion measuring approximately 1.4 x 1.2 cm (series 4/147). No definite associated signal abnormality is identified on T2-weighted images. There may be associated mild relative hyperenhancement to the remainder of the pancreatic parenchyma on subtraction images (series 100/30). This corresponds to the faintly enhancing lesion seen on the outside hospital CT (series 6/56).ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Significant main pancreatic ductal dilatation and moderate pancreatic parenchymal atrophy with a 1.4 cm focus of restricted diffusion corresponding to the faintly enhancing lesion seen on outside hospital CT and compatible with the stated history of pancreatic neuroendocrine tumor. No definite liver metastases or other sites of disease.
