66 year old male patient with renal mass on CT. Evaluate for a pancreatic mass. ABDOMEN:LIVER, BILIARY TRACT: No significant abnormality noted.SPLEEN: No significant abnormality noted.PANCREAS: There is a 1.5 x 2.0 cm lobulated, septated cystic lesion within the head of the pancreas (image 55, series 1304), which appears to communicate with the main pancreatic duct (image 56, series 1304). An additional lobulated, septated cystic lesion within the head/uncinate process measuring 2.3 x 2.2 cm (image 72, series 1304) also appears to communicate with the pancreatic duct. There is no suspicious enhancement of either lesion. The main pancreatic duct is not dilated.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: There is a 6.7 x 4.8 x 4.4 cm multiseptated right upper pole renal sinus cyst without suspicious features or enhancement. A subcentimeter lesion within the left lower pole is not hyperintense on T2 images, but is too small to fully characterize. Multiple additional bilateral T2 hyperintense lesions likely represent cysts. No evidence of hydronephrosis. RETROPERITONEUM, LYMPH NODES: Susceptibility artifact within the infrarenal IVC secondary to an IVC filter. BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Two dominant cystic pancreatic lesions without suspicious features which appear to communicate with the pancreatic duct likely represent sidebranch type IPMNs.2.Complex left renal sinus cyst without suspicious enhancement. No hydronephrosis.
