Diagnostic value of imaging in patients with clear cell papillary renal cell carcinoma: A case series and literature review

Abstract

AbstractClear cell papillary renal cell carcinoma (CCPRCC) is a newly classified renal cell carcinoma with a low degree of malignancy. Its imaging features have not been studied deeply. Therefore, we reviewed the imaging features of CCPRCC. Solid CCPRCC shows high echo or isoecho mass on conventional ultrasound. Contrast enhanced ultrasound shows “fast forward and slow backward, uneven high enhancement”. Computed tomography shows high enhancement and maximum enhancement in the cortical‐medullary phase. Magnetic resonance imaging shows slightly low T1WI and high T2WI. This article aims to improve the understanding of CCPRCC by clinical radiologists and promote the accurate.
