Enhanced CT scan of the head, chest, and abdomen (Figure 1A) suggested a round-soft tissue density in the middle and lower part of the left kidney, CT about 40 HU, size of approx. 4.4 cmx3.9 cmx4.8 cm with a clear border. The treatment was completed on June 27, 2019. The most recent follow-up (August 4, 2020) suggested no metastasis (Figure 1B).

CT showed a large irregular mixed density (approx. 7.0 cmx8.6 cmx8.0 cm) in the left abdomen, which was further suggestive of nephroblastoma (Figure 3A). December 11, 2018, the head, chest, and abdomen were examined by MRI; the hip X line did not appear abnormal on April 21, 2018 (Figure 3B). During the most recent follow-up on December 7, 2020, MRI suggested no metastases of the head, chest, and total abdominal and pelvic (Figure 3C).
