WebbMethemoglobin and protein shorten the T1 of the fluid and cause the cysts to become hyperintense on T1-weighted imaging. Although these hemorrhagic or proteinaceous cysts remain benign, there can be overlap in appearance with renal cell carcinoma (RCC), with both showing hyperintensity on T1-weighted imaging, making differentiation critical. WebbMagnetic resonance (MR) imaging may be helpful for differentiating between angiomyolipomas with minimal fat and clear cell renal cell carcinomas; however, differentiation between angiomyolipomas with minimal fat and papillary renal cell carcinomas often is not possible on the basis of MR imaging.
