Non-contrast imaging characteristics of papillary renal cell carcinoma: implications for diagnosis and subtyping.
Current radiographic guidelines suggest unenhanced renal lesions < 20 Hounsfield Units (HU) are overwhelmingly benign, requiring no further evaluation. We evaluate our experience with papillary renal cell carcinoma (pRCC) presenting with low pre-contrast attenuation and the relationship of attenuation with histologic pRCC subtype. We reviewed our institutional kidney cancer database for patients with pT1 or […]
