title: Solitary Retroperitoneal Metastasis as the Initial Site of the Relapse of Osteosarcoma Revealed by FDG PET/CT.
abstract: Adjuvant and neoadjuvant chemotherapy has altered the metastatic pattern of osteosarcoma. Overwhelming majority of the metastases from osteosarcoma are to the lungs and to the bones. Uncommon metastases to other sites can occur but usually accompany pulmonary and skeletal metastases. Here, we describe an asymptotic 14-year-old boy with solitary retroperitoneal metastasis as the initial relapse of osteosarcoma revealed by FDG PET/CT.
