CT Solid Homogeneous Enhancement
CT of an Enhancing, Hyperdense, Renal Nodule CT through the kidneys reveal a hyperdense nodule that measured 56.HU. Following contrast, the density of the nodule increased to 101.8 HU. An enhancing mass in the kidney is highly suspicious for a renal cell carcinoma Ashley Davidoff MD TheCommonVein.net 135674
CT Solid Heterogeneous Enhancement
Axial CT ? Unilateral Solid Mass in the Kidney Axial CT through the mid kidneys in a patient with hematuria shows a 2cms heterogeneously enhancing mass on the anterior lip of the right kidney. The most likely diagnosis is a renal cell carcinoma (RCC) Ashley Davidoff MD TheCommonVein.net 130186

Solid Cystic and Calcified
Bosniak IV Renal Cyst on CT CT of the upper abdomen in axial projection shows a complex cyst in the left upper pole (yellow arrowhead), coarse rounded calcifications along septations (white arrowhead) and a soft tissue nodule (green arrowhead) consistent with a Bosniak IV lesion.

Cystic Renal Cell Carcinoma (RCC) with Clear Cell Histology Cystic renal cell carcinoma with dystrophic calcification in the mid portion of the left kidney. Pathology reveals cystic renal cell carcinoma with clear cell histopathology Ashley Davidoff MD
CT Bilateral Disease
CT with Bilateral Solid and Cystic Masses CT with contrast, reconstructed in the coronal plane shows bilateral solid masses in the upper poles of the kidneys consistent with bilateral renal cell carcinoma (RCC?s). This patient has acquired cystic disease of Chronic renal failure Additional key words: renal Ashley Davidoff MD TheCommonVein.net
CT Solid Spontaneous Hemorrhage
Spontaneous Subcapsular Hemorrhage Patient has acquired cystic disease of chronic failure and presents wit spontaneous subcapsular hemorrhage of the left kidney. A hemorrhage from a malignancy known to occur as a complication of this entity was suspected. At the inferior aspect of the hemorrhage there is extension of the process into the retroperitoneum giving the appearance of the ?spider web sign? or ?cobweb sign?

CT Diffuse Infiltration and Renal Vein Involvement
Delayed Nephrogram Caused by Invasive renal Cell Carcinoma and Renal Vein Thrombosis – CT CT of the upper abdomen in axial projection shows an enlarged right kidney in cortical phase, effaced by an infiltrating renal cell carcinoma invading the renal parenchyma, intrarenal collecting system, the IVC and the left renal vein. The left kidney is in the nephrogram phase, so at this time of contrast handling there is evidence of delayed nephrographic phase of the right kidney. The right kidney also demonstrates the face less kidney sign which implies that the the normal appearance of the renal sinus on cross-sectional imaging is absent.

US Solid Enhancing
This series of US scans (a,b) and CT scans (c,d) show a solid hypervascular mass in the lower pole of the right kidney. The findings are characteristic of a renal cell carcinoma. Note the complex lesion in the left lower pole. A second RCC is included in the differential diagnosis. 39056c code GU kidney mass hypervascular RCC radiologists and detectives Ashley Davidoff MD 39056c
