case_images: (A) T2-weighted MRI showing a tumor with a high signal intensity (indicated by the yellow arrow) in the right superior pole of the renal vein. (B) Plasma renin activity values at various sampling points in the vasculature of the renal veins. (C) Upper branch of the right renal vein in angiography. (D) The tumor morphology was observed using hematoxylin-eosin staining under a light microscope (10 x 40).

case_images: T2-weighted MRI, as shown in  Figure 1A . The primary features of this case included resistant hypertension, elevated We performed selective angiography during the selective venous sampling, and the results indicated that the PRA level was 52.1 ng/mL/h in the right superior pole renal vein, 12.7 ng/mL/h in the right lower pole renal vein, 13.9 ng/mL/h in the left renal vein, and 11.5 ng/mL/h in the lower inferior vena cava ( Figures 1B, C ). A pathological analysis revealed that the tumor cells originated from the juxtaglomerular region ( Figure 1D ).
