Male 50 years old Reason: Newly diagnosed Follicular Lymphoma in which staging CT scan showed an abnormal left renal mass that needed further evaluation History: Follicular Lymphoma CT scan showed an abnormal left renal mass that needed further evaluation ABDOMEN:LIVER, BILIARY TRACT: Liver is normal in morphology. No suspicious hepatic lesions. Hepatic and portal veins are patent. Spleen is top normal in size.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Right kidney enhances homogeneously. There are few scattered T2 hyperintense foci in the right kidney that do not enhance and are compatible with cysts. In the left kidney, there is a T1 hyperintense lesion that is T2 hypointense involving the posterior midpole of the left kidney measures 1.4 x 1.2 cm on image 95/ series 24. The lesion does not show definite internal enhancement on postcontrast imaging (image 94/series 101) and is probably a hemorrhagic cyst. The lesion seen on CT along the medial aspect of the kidney is T2 hyperintense measuring 1.7 x 1.4 cm on image 32 of series 23. This lesion also does not show any appreciable enhancement and likely represents a cyst.RETROPERITONEUM, LYMPH NODES: Retroperitoneal lymph nodes measurements provided below.BOWEL, MESENTERY: Mesenteric lymph nodes with haziness of the mesentery persists.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.INDEX LESION MEASUREMENTS (Current exam date/time: 7/8/2016 13:30:00)LEFT RENAL MASS: 1.7 x 1.4 cm (Image 32, Series 23); 2.2 x 1.5 cm on prior (6/23/2016) (Image 93, Series 3).LEFT PARA-AORTIC ADENOPATHY: 2.1 x 1.0 cm (Image 86, Series 25); 2.2 x 1.2 cm on prior (6/23/2016) (Image 94, Series 3).AORTOCAVAL ADENOPATHY: 2.0 x 1.0 cm (Image 90, Series 25); 1.7 x 1.1 cm on prior (6/23/2016) (Image 92, Series 3).LEFT RENAL LESION 2: 1.4 x 1.2 cm (Image 95, Series 24).
1.Lesion seen on CT compatible with a cyst.2.Second left renal lesion along the posterior aspect of the kidney likely represents a hemorrhagic cyst (within the limitation of its small size and proximity to the renal parenchyma)
