Figure 3. The patient in Figure 2 recurred with an isolated deposit anterior to the heart 1.5. years after initial therapy that was just outside of the previously irradiated field. This recurrence is depicted on PET/CT in (A) sagittal and (B) axial. He was treated with 50 Gy in 5 fractions using a stereotactic body radiation therapy approach in (C) dose-volume histogram; (D) dose distribution in the axial plane; and (E) dose distribution in the sagittal plane, and he remains disease-free 5 years after his initial presentation and 3.5 years after treatment of his recurrence.
