title: Extraskeletal osteosarcoma: An uncommon variant with rare metastatic sites detected with FDG PET/CT.
abstract: Extraskeletal osteosarcoma (ESOS) is a rare malignancy, which commonly presents with metastatic disease. Like their osteogenic counterparts, these tumors commonly metastasize to lungs and bones. We report the fluoro-deoxyglucose positron emission tomography findings in a case of ESOS presenting with a combination of rare metastatic sites such as brain, kidney and the bone marrow.
