72-year-old female. HOP cystic mass. Evaluate for cystic lesion in head of pancreas. ABDOMEN:LIVER, BILIARY TRACT: A few small hepatic cysts. No suspicious hepatic mass. No biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: Multilocular 2.7 x 1.8 cm cystic lesion in the pancreatic head with multiple thin septations (series 1301, image 16). The main pancreatic duct appears to communicate with this lesion (series 801, image 25), making it suspicious for a side-branch IPMN. No mural nodularity or enhancement on post-contrast sequences. Physiologic response of the pancreas to secretion. No main pancreatic ductal dilatation.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: A few subcentimeter renal cysts bilaterally. No hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Multilevel degenerative disk disease of the lumbar spine with moderate to severe stenosis at L4-L5.OTHER: No significant abnormality noted.
Multilocular cystic lesion in the pancreatic head is likely a side-branch IPMN. No significant internal nodularity or enhancement to indicate malignant degeneration.
