A-F Imaging findings 3 months after thrombectomy. Physical examination shows swelling in the right subclavicular lesion (A), and PET/CT of the chest demonstrates FDG uptake (SUVmax: 7.3) in the tumor (B). MRI shows a significant increase in the size of the remaining recurrent tumor in the subclavicular vein (T1-weighted axial (C), T2-weighted axial (D), fat-suppressed contrast-enhanced T1-weighted axial (E), and coronal (F) sections). G-J Postoperative pictures (G and H) and radiographs (I and J) of the performed forequarter amputation combined with partial chest wall resection
