Male 80 years old status post partial right nephrectomy for right renal cell carcinoma. Surveillance scan. Poor renal function, so no contrast. ABDOMEN:LIVER, BILIARY TRACT: The liver is size and morphology. No intra or extra hepatic biliary ductal dilatation or ascites. No suspicious hepatic lesion.SPLEEN: No significant abnormality noted.PANCREAS: T2 hyperintense lesions in the pancreatic head and body are again seen. The largest measures 1.6 cm (series 5, image 22), previously 1.1 cm. Several T2 hyperintense lesions were not seen on the prior exam however it is uncertain whether this is related to technique and respiratory motion. They likely represent sidebranch IPMNs. There is no pancreatic ductal dilatation.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Stable postoperative findings of partial right nephrectomy. Along the superior aspect of the right kidney an exophytic, lobulated soft tissue focus abutting the liver is unchanged and, given the susceptibility over time, is favored to represent postsurgical change. Within the limits of a noncontrast exam, there is no evidence of focal recurrence.Again seen within the left kidney are multiple renal sinus cysts cysts, some are simple while others have thin septations 5 appears similar to the previous exam.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Colonic diverticulosis without evidence of diverticulitis.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Given stability over time, the lobular soft tissue along the resection margin in the right kidney is favored to represent postsurgical change. No definite evidence of local recurrence within the limitations of a noncontrast exam.2.No evidence of metastatic disease.
