61-year-old man with history of pancreatic and hepatic cysts. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in size and morphology. There are numerous simple hepatic cysts again noted and unchanged in size. Of these, a few appear to be hemorrhagic with high T1 signal (13/69), but do not enhance. The large complex cystic lesion with heterogeneous internal T1 and T2 signal (7/36) measures 107 x 98 mm, previously 125 x 115 mm. On postcontrast imaging, there is no internal enhancement. This lesion causes mild local mass effect on the adjacent duodenum and common bile duct, however there is no biliary obstruction or biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: The multiloculated cystic lesion in the tail of the pancreas (500/30) measures 57 x 28 mm, previously 59 x 36 mm. Indication of the pancreatic duct is not clearly visualized. The remaining pancreatic parenchyma appears normal.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Small ventral hernia.OTHER: No significant abnormality noted.
1.Complex cystic lesion of the liver continues to decrease in size, possibly representing a large complex cyst or biliary hamartoma.2.Multiple additional liver cysts unchanged with benign characteristics.3.Stable cystic lesion in the pancreatic tail, likely a side branch IPMN or a serous cystadenoma.
