History of neuroendocrine tumor in head of pancreas. ABDOMEN:LIVER, BILIARY TRACT: A simple cyst in segment 6/7 measures up to 3 cm. Additional scattered subcentimeter cysts are also present. The previously described tiny focus of arterial enhancement in the inferior right hepatic lobe is not well seen on this examination. No suspicious hepatic lesions are identified. The common bile duct measures up to 9 mm and tapers smoothly distally without obstructing stone or lesion identified. The hepatic vasculature appears patent.SPLEEN: There is a lesion within the spleen (series 14, image 31) measuring 2.3 x 2.8 cm which demonstrates isointense T1 and T2 signal as well as heterogeneous early enhancement with filling in on delayed imaging. The lesion appears grossly similar to the outside 12/19/2013 examination allowing for differences in technique.PANCREAS: There is significant pancreatic ductal dilation measuring up to 7 mm which abruptly tapers at the level of the pancreatic neck, and is again mildly prominent near the ampulla. At the level of the narrowing, there is a tiny hyperenhancing intraductal lesion (series 13, image 48) measuring up to 5 mm. There is moderate-severe atrophy of the pancreatic body and tail appearing similar to prior with sparing of the pancreatic head.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: A small duodenal diverticulum is present in the third portion of duodenum.BONES, SOFT TISSUES: Degenerative changes of the spine.OTHER: No significant abnormality noted.
1.5 mm hyperenhancing intraductal lesion at the pancreatic head/neck with resultant ductal dilation compatible with patient's known history of intraductal neuroendocrine tumor, not significantly changed. 2.A 2.8 cm enhancing splenic lesion which is nonspecific but similar to 2013 exam and thus most likely benign.
