Abstract
A 60-year-old male with malignant melanoma in the 3rd digit of the right foot undergoes disarticulation and excision of 14 inguinal nodes which does not show metastases. After 6 months, physical exam reveals ten small black “moles” on the anterior and inner part of the right thigh. A PET/CT scan is requested and shows that the “moles” have low-grade FDG uptake, SUVs = 0.9, 0.7, and looking like reconstruction artifacts in the attenuation corrected (AC) images (Fig. 10.1). The non-attenuation corrected (NAC) images, however, confirm the FDG-avidity of these lesions. Some of the “moles” are not seen in the AC images. The CT images confirm the presence of these lesions.
