case_images: (A, B) Computed tomography revealed a slightly high-density nodule at the lower pole of the left kidney for case one, with a diameter of about 2.5 cm and a CT value of 57 HU on plain scan with no obvious strengthening. (C, D) CT demonstrated a 1.6x1.3 cm round high-density nodule in the right kidney of case 2 with a CT value of about 80HU on plain scan. No enhancement after intravenous administration of contrast was noted.

case_images: The mass was classified as Bosniak type III ( Figures 1C, D ).
case_images: Both the pathological manifestations of the tumors from the aforementioned two patients were consistent with typical PRNRP. The HE staining showed papillary or tubular structures, the surface was covered with a monolayer of eosinophils, the cytoplasm was granular, with small nuclei away from the cytoplasmic top of the basement membrane. The immunohistochemical phenotype was GATA3 (+), vimentin (-) (A, B: Case 1 C, D Case 2).
