History of chronic pancreatitis complicated by pseudocysts. Ascites. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, size, signal intensity and enhancement without a focal lesion. The vessels are patent.Status post cholecystectomy. There is some mild central intrahepatic and extrahepatic biliary ductal dilatation to the level the pancreatic head. No focal lesion is evident.Moderate perihepatic ascites.SPLEEN: The spleen is normal in size without a focal abnormality. The splenic vein is atretic.PANCREAS: There is mild decrease in the intrinsic T1-weighted signal intensity of the pancreatic parenchyma compatible with the stated history of chronic pancreatitis. It demonstrates normal enhancement. The main pancreatic duct is normal in caliber. There is a multiloculated cystic T2 hyperintense fluid collection adjacent to the pancreatic tail measuring up to 6.3 x 4.6 cm with some fluid fluid levels and thin rim peripheral enhancement most compatible with a pseudocyst. This abuts the greater curvature of the stomach.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Pericolonic collateral vessels are noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.6.3 x 4.6 cm multilobulated cystic lesion adjacent to the pancreatic tail is compatible with a pseudocyst given the history of chronic pancreatitis.2.Status post cholecystectomy with mild intra and extra hepatic biliary ductal dilatation which may reflect postcholecystectomy state. No discrete lesion is evident.
