Fig. 1 A 73-year-old woman with multiply recurrent papillary thyroid carcinoma (tall-cell variant) presented with gross disease recurrence in the right tracheoesophageal groove. Intraoperatively, the disease was adherent to the trachea and esophagus and was deemed unresectable. She received 59.4 Gy to the upper neck and mediastinum, and 70 Gy to the area of gross disease, in 33 fractions, using a “dose-painting” technique. (a) A high-neck axial slice, demonstrating the planning target volume (PTV)59.4 (red) and parotid (cyan and pink) contours, and representative isodose curves. (b) Upper mediastinal axial slice, demonstrating the PTV59.4 (red) and PTV70 (green) contours, plus isodose curves. (c) Sagittal slice, demonstrating the PTV59.4 (red) and PTV70 (green) contours, plus isodose curves. (d) Dose–volume histogram for the patient’s treatment plan.
