A. Sagittal (top) and coronal images of baseline PET/CT scan. Detailed legend: These images of patient no 4 show abnormal hypermetabolism at the left acromioclavicular joint, and at T6 and L5 vertebrae, along with paravertebral soft tissue involvement. Initial MRI evaluation of the lumbar spine of the same patient revealed only the lesion at the area of L4 – L5 vertebrae with paravertebral mass. B. Follow-up PET/CT scan after treatment. Detailed legend: These images of patient no 4 post-treatment demonstrate decreased FDG uptake at T6 and L5 vertebrae, and no uptake at the paravertebral tissues.
