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.
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.
