Radiologic response to cisplatin and paclitaxel. a Axial MRI demonstrates postoperative changes following surgical resection of popliteal mass without evidence of residual disease. b Axial contrast-enhanced CT images following neoadjuvant chemotherapy demonstrate decreased size of left external iliac nodes, consistent with response to therapy. On chemotherapy at (c) 1 month and (d) 4 months after presentation, both the right lung mass and nodule have markedly improved consistent with response to therapy
