Presentation
Patient with a past medical history of coronary artery disease, rheumatoid arthritis, and current everyday smoking, presents to Urology clinic for evaluation of intermittent gross hematuria for the past 2 months.
Patient Data
Non-contrast and renal excretory phase CT images demonstrate a 5.1 cm hypoenhancing left renal mass centered in the left renal pelvis with infiltration of the upper renal pole and extension to the level of the uretero-pelvic junction.
Case Discussion
Patient underwent radical nephrectomy. Pathology revealed a high-grade papillary urothelial carcinoma.
Key points:
On CT, papillary urothelial carcinoma presents as a tissue mass centered in the renal pelvis which with a degree of enhancement that is less than renal cell carcinoma and adjacent renal parenchyma.
It can show an infiltrative pattern of growth into the renal parenchyma without distortion of the renal contour.
On MRI, it demonstrates hypointense signal on T1 and T2-WI and, again, typically enhances to a lesser degree than adjacent renal parenchyma.
