RESUMEN
Objective To evaluate the diagnostic value and limitation of MRI for chromophobe renal cell carcinoma.Methods MRI features of 5 cases with pathology proved chromophobe renal cell carcinoma were analyzed retrospectively.Results All tumors showed homogenous isoin-tensity or slightly hypointensity on T1 weighted images and isointensity or slightly hyperintensity on T2 weighted images.Slightly hyperintensity were showed on DWI images,the mean ADC value of tumors was 1.42×10-3 mm2/s.On the contrast enhanced images,all the mass showed slight to moderate enhancement ,1 case had spoke-wheel-like enhancement,1 case showed flowed out blood vessels in the tumor.Conclusion The preoperative diagnosis is difficult for chromophobe renal cell carcinoma,MRI is a valuable method which could provide useful information for qualitative diagnosis.
