17-year-old girl with invasive squamous cell carcinoma at her distal left index finger and congenital keratitis, ichthyosis, deafness (KID) syndrome. A, CT image depicts several soft tissue lesions over the frontal scalp. B, 18FDG-PET and C, 18FDG-PET/CT, show multiple subcutaneous soft tissue lesions over the scalp and posterior to the left pinna with increased metabolic activity and measured standardized uptake values up to 7.4. There is no evidence of erosion or other bony changes of the calvarium subjacent to these soft tissue lesions. These lesions are proven benign by histopathology and are a complication of her KID-syndrome. D, Whole body 18FDG-PET scan with increased radionuclide uptake at the distal left index finger (arrow) (SUV 3.1) and at multiple soft tissue lesions over the scalp (SUV 7.4).
