case_images: A computed tomography (CT) scan conducted 17 years ago revealing a mass with a maximum cross-sectional diameter of 13 x 8 cm in the right kidney is shown. Several calcifications within the tumor are observable.

case_images: Seventeen years previously, the computed tomography (CT) examination revealed a 13-cm right renal mass without gross hematuria ( Figure 1 ).
case_images: Abdominal incision and tumor status in vivo and in vitro. (A) Abdominal distension, mainly on the right side in the supine position, is observable. (B) The hypervascularized tumor after excision is shown. (C) The skin incision selected was a midline abdominal incision, along with right upper abdominal oblique and left midline transverse incisions. (D) The veins on the surface of the mass are noticeably enlarged and dilated.

case_images: Physical examination in the supine position revealed significant abdominal distension, mainly on the right side ( Figure 2A ). Due to the massive size of the tumor, midline abdominal, right upper abdominal oblique, and left midline transverse incisions were made ( Figure 2C ). Abdominal cavity exploration revealed tumor surface veins were significantly dilated and tortuous, making separation prone to bleeding ( Figure 2D ). Postoperatively, the tumor weighed 5.5 kilograms ( Figure 2B ).
case_images: Computed tomography scans show a massive abdominal mass. (A) CT scan revealing a massive abdominal mass with dimensions of approximately 25.8 x 22.1 x 15.6 cm exhibiting irregularity and enhancement is shown. (B) Vascular reconstruction revealing an extremely rich blood supply for the mass and the presence of a few calcifications within the mass is shown.

case_images: A large hypervascularized mass occupying the right side of the abdomen without evidence of direct inferior vena cava invasion was evident on computed tomography urography (CTU) ( Figure 3 ).
case_images: Preoperative right renal artery embolization. (A) Angiography of the right kidney revealed abundant blood supply to the right renal tumor. (B) Embolization of the right renal artery revealed that the blood supply to the tumor was blocked.

case_images: Preoperatively, right renal artery embolization was performed to reduce tumor blood supply and minimize intraoperative bleeding ( Figure 4 ).
