87-year-old male with stage IV chronic kidney disease. Evaluate for renal mass. Motion artifact limits evaluation.ABDOMEN:LIVER, BILIARY TRACT: No significant abnormality noted.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: There are multiple bilateral T1 hyperintense and T2 intermediate signal foci within the kidneys most likely proteinaceous cysts. Additionally, there are multiple T2 hyperintense and T1 hypointense subcentimeter foci within bilateral kidneys compatible with cysts. There is a T1 and T2 heterogeneous lesion in the right upper pole measuring 2.1 x 1.8 cm, previously measuring 5.2 x 4.0 cm on the CT9/11/2015.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Significant interval decrease in size of the right upper pole exophytic mass when compared to prior sonographic and CT imaging. Although lack of contrast limits evaluation, given significant interval decrease in size, an involuting hemorrhagic cyst is favored.2.Multiple bilateral proteinaceous and simple cysts.
