The Angio Computer Tomography scan performed at three weeks after embolization showed a reduction in size of the tumor. In March 2018 patient underwent bone resection and reconstruction with a G.M.R.S. tumor prosthesis. Resection was performed in a complex team involving also two vascular surgeons. The pathology exam confirmed it was a renal cell carcinoma bone metastasis. Results. At one week after the surgical procedure, the operative wound was healing, the patient had no pain, and he was gradually regaining ambulation. Conclusion. Surgical treatment of such neoplastic pathology is difficult and involves a multidisciplinary approach consisting of disciplines such as oncology, orthopedics, vascular surgery, and pathology.
