Evaluate pancreatic pseudocyst evolvement. History of Crohn's disease and chronic pancreatitis. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology size, signal intensity and enhancement. No intrahepatic or extrahepatic biliary ductal dilatation. Normally distended gallbladder without gallstones.SPLEEN: Trace perisplenic fluid. Otherwise the spleen is normal in morphology and size.PANCREAS: Compared to the recent 1/2/2015 MRI there is mild increase in interstitial edema-type signal of the pancreatic parenchyma and peripancreatic inflammatory fluid/fat stranding. However the peripancreatic peripherally enhancing lobular fluid collections extending superiorly towards the porta hepatis measuring approximately 3.1 x 1.7 cm (series 1201/192) and anteroinferiorly towards the lesser curvature of the stomach measuring 1.4 cm (series 1201/102) are significantly decreased in size. There is heterogeneous enhancement of the pancreatic parenchyma predominantly affecting the body but no evidence of parenchymal necrosis or hemorrhage. There is narrowing and irregular mild dilatation of the pancreatic duct which is improved from the 1/2/2015 study.Please note that the retroperitoneal heterogeneous mass about the SMA noted on the 10/26/2015 study has essentially resolved.There is narrowing of the SMV splenic vein and portal vein confluence without discrete thrombus.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Partially duplicated right collecting system.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Mild right basilar atelectasis. Susceptibly artifact from sternotomy hardware.
Findings compatible with acute edematous interstitial pancreatitis superimposed on chronic pancreatitis with short interval decrease in the peripancreatic fluid collections.
