Asymptomatic pancreas tail mass. ABDOMEN:LIVER, BILIARY TRACT: Fatty infiltration of the liver. Cholelithiasis within a contracted gallbladder without specific evidence of acute gallbladder inflammation.The liver has normal morphology, signal intensity and enhancement. No focal suspicious lesion, biliary ductal dilatation or vascular abnormality.SPLEEN: Mild splenomegaly with the spleen measuring 14 cm in craniocaudal dimension.PANCREAS: The cystic lesion in the tail of the pancreas now measures approximately 3.2 x 2.9 cm (series 7/19), compared to 2.4 x 2.1 cm previously. The lesion has a lobular contour and is composed of numerous small cysts the largest of which measures less than a centimeter. There is postcontrast enhancement of the septations without a discrete enhancing mural nodule. There is no associated pancreatic ductal dilatation or pancreatic parenchymal atrophy. The lesion does not appear to communicate with the main pancreatic duct.ADRENAL GLANDS: Stable subcentimeter left adrenal nodule demonstrating signal loss on out of phase imaging compatible with a benign lipid rich adrenal adenoma.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Degenerative changes of the spine. Tortuous abdominal aorta.OTHER: No significant abnormality noted.
Mild interval growth in the cystic pancreatic lesion, appearance most suggestive of a serous cystadenoma. Given the interval growth, further evaluation and possible histologic sampling should be considered, particularly as an atypical mucinous neoplasm cannot be excluded.
