Presentation
Gradual progressive right flank pain.
Patient Data
Right renal lower pole well-defined heterogeneous solid mass lesion measuring about 8 x 7 cm with areas of necrosis and internal vascularity, clear surrounding fat planes. No stones or back pressure changes.
Right renal lower pole well defined solid mass lesion measuring about 9 x 8 x 7 cm in its maximal AP, TR & CC dimensions respectively (T2a). It shows heterogeneous post-contrast enhancement. Large caudal area of necrosis, 6 x 5 cm.
The mass displaces the right ureter anteriorly with no evidence of obstruction and also abutting the IVC with no evidence of infiltration. Patent right renal vein with no intraluminal thrombus. Clear surrounding fat planes with no evidence of extracapsular extension (confined to the kidney).
No renal stones or back pressure changes. Preserved excretory function of the kidney. No nodal involvement. Left renal lower calyceal stone is noted.
Case Discussion
Solid renal mass (>7 cm) confined to the kidney with no nodal or distant metastasis. This is most likely renal cell carcinoma stage II.
