Kidneys
2. Findings and Diagnosis
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.
