Physical examination revealed painful purpura with a well-healed local incision scar (of approximately 4 cm in length) on the right chest wall (Figure 1). During the operation, the tumor-supplying arterial branches, including the right internal thoracic artery, axillary artery, and multiple intercostal arteries, were treated with vincristine (1.2 mg) infusion, and embolization was performed using pingyangmycin iodide oil emulsion and polyvinyl alcohol (PVA) of 300-500 mum-diameter (Supplementary Figures 1, 2).
Computed tomography (CT) imaging showed enhancement of chest wall lesions, atelectasis of the right lung, right encapsulated pleural effusion, and pleural thickening.

On enhanced chest computed tomography (CT) scan (Figure 2), in addition to the uneven enhancement of the chest wall lesions with unclear margins, pneumonia with atelectasis of part of the right lung, thoracic malformation, right encapsulated pleural effusion, and pleural thickenings were also observed. During the operation, the tumor-supplying arterial branches, including the right internal thoracic artery, axillary artery, and multiple intercostal arteries, were treated with vincristine (1.2 mg) infusion, and embolization was performed using pingyangmycin iodide oil emulsion and polyvinyl alcohol (PVA) of 300-500 mum-diameter (Supplementary Figures 1, 2).
Magnetic resonance imaging (MRI) showed enhancement of chest wall lesions, atelectasis of the right lung, right encapsulated pleural effusion, and pleural thickening.

Similar findings were observed under magnetic resonance imaging (MRI) (Figure 3). However, it should be noted that the skin color of the lesions (Figure 4), platelet count (the comparison is shown in Supplementary Figure 3), and coagulation function significantly improved 4 days after surgery.
