Reason: Hypervascular pancreatic tail lesion History: see above. History of kidney cancer status post nephrectomy and bilateral adrenalectomy ABDOMEN:LIVER, BILIARY TRACT: Right hepatic subcentimeter T2 hyperintense lesion is too small to characterize but unchanged.SPLEEN: No significant abnormality noted.PANCREAS: Lesion in the pancreatic tail measuring 2.6 x 2.3 cm is hypointense on T1 and mildly hyperintense on T2 without diffusion restriction. This lesion demonstrates patchy enhancement on postcontrast images. Of note, signal intensity differs from that of the spleen.ADRENAL GLANDS: Status post bilateral adrenalectomy.KIDNEYS, URETERS: Status post right nephrectomy. Retroaortic left renal vein. No enhancing tissue in the nephrectomy bed.RETROPERITONEUM, LYMPH NODES: No retroperitoneal lymphadenopathy.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Enhancing lesion within the pancreatic tail is likely neoplastic. A metastatic lesion is favored, with a neuroendocrine tumor considered less likely.
