CT Solid Homogeneous Enhancement
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

CT Solid Heterogeneous Enhancement
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)

CT Solid Mass with Heterogeneous Components
Solid Cystic and Calcified
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.

CT Hypovascularity Papillary Form
64 year old male
IVP at 20 seconds shows a mass in the right lower pole and 20 minute film conforms the finding.. CT shows a deforming mass and US shows mildly hypoechoic mass. Pathology reveals papillary cell RCC

Cystic Renal Cell Carcinoma CT and Pathology
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

CT Bilateral Disease
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

CT Solid Spontaneous 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 Focal Mass and Renal Vein Involvement
Renal Cell Carcinoma of the right kidney shows extension of hypervascular tumor thrombus into the right renal vein and IVC
Ashley Davidoff MD
CT Diffuse Infiltration and Renal Vein Involvement
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.

RCC Angiography
IVP and Angiogram
a IVP in the nephrographic phase shows an enhancing mass off the upper pole of the right kidney.
b – IVP in the pyelographic phase shows an a deformity of the upper and outer part of the right kidney
c – Nephrographic phase of the arteriogram confirms a hyper vascular mass
d Renal angiogram with epinephrine confirms arterial enhancement of the mass with constriction of the normal vessels and failure of the abnormal response
Ashley Davidoff MD
On CT there is dystrophic calcification. On angiography there is hypervascularity, neovascularity, AV shunting. Excretory phase after angiography shows distorted calyces
