History of enlarging pancreatic cyst. ABDOMEN: Artifact from aortic stent graft limits evaluation of the retroperitoneum and distorts many of the imaging sequences.LIVER, BILIARY TRACT: Mildly prominent common bile duct up to 10 mm tapering smoothly at the ampulla without a filling defect or discrete mass lesion. This may be related to the patient's postcholecystectomy state.SPLEEN: No significant abnormality noted.PANCREAS: The pancreatic distal body well-defined cystic lesion measures 2.4 x 2.3 cm (series 12/29), compared to 2.6 x 2.3 cm previously. Additional punctate pancreatic tail foci are also unchanged. The main pancreatic duct is normal in caliber. There is no mural nodularity of the lesion. Otherwise limited nonenhanced evaluation of these cysts is unremarkable.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Small hiatal hernia.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Limited study due to artifact and lack of intravenous contrast shows a stable pancreatic body 2.4 cm cystic lesion without mural nodularity. It is essentially unchanged from 5/5/2015, but increased in size since 08/13/2013 CT.
