Parosteal osteosarcomas are uncommon neoplasms that typically affect the long bones. Primary involvement of a rib is very rare. The imaging features of a parosteal osteosarcoma involving a rib are described, including the magnetic resonance imaging features, which have not been previously been reported in the literature.
