case_images: On follow-up imaging, a new 6 mm wide hypermetabolic nodule was identified in the distal thigh (Figure 1), outside of the irradiated field, as well as an in-transit metastasis.
case_images: Transverse grayscale ultrasound image. The hypoechoic mass (large arrow) is deeply located in the subcutaneous adipose tissue. The needle (small arrows) is visualized within this mass before deploying the iodine-125 radioactive seed.

case_images: An iodine-125 radioactive seed was inserted under ultrasonography in each nodule (Figure 2), and radiography confirmed adequate positioning (Figure 3).
case_images: Lateral X-ray of the distal third of the thigh demonstrating the seeds (arrows) projecting on the soft tissue anteriorly and posteriorly to the distal femur.
