A case of clear cell papillary renal cell tumor and literature analysis
Clear cell papillary renal cell tumor(CCPRCT)is a renal tumor with low malignant potential.This article retrospectively analyzed the clinical and radiographic data of middle-aged male patient with CCPRCT in the First Affiliated Hospital of Jinan University in August 2021 and reviewed the relevant literature..Ultrasound showed a hypoechoic nodule at the upper pole of the left kidney,measuring about 3.8 cm × 2.6 cm × 3.0 cm,with clear borders,and a small patchy echogenic area within the nodule,part of the nodule protruding outside the kidney.Color Doppler flow imaging(CDFI)showed a little blood flow signal around the nodule.Contrast-enhanced ultrasound(CEUS)showed fast-forward and slow-retreat,inhomogeneous hyperenhancement.Magnetic resonance imaging(MRI)showed a lobulated mass at the upper pole of the left kidney,measuring about 4.0 mm × 2.9 mm × 2.7 mm,with clear borders and smooth edges,predominantly hyposignal on T1WI and equal-high signal on T2WI,with a honeycomb-shaped hypersignal foci and a low-signal component on T2WI within the mass.Enhancement scan showed obvious enhancement of the solid component in the arterial phase,slightly reduced enhancement in the equilibrium phase,and delayed enhancement slightly lower than normal renal parenchyma;the T2 low-signal strips within the mass were delayed enhancement,and the mass was unevenly high-signal on diffusion weighted imaging(DWI).MRI showed occupying lesions in the upper pole of the left kidney,which were considered to be a high probability of renal cancer.
