摘要
Parosteal osteosarcomas are rare, low-grade juxtacortical variant of osteosarcoma, especially in the jaws, representing 1.6% of all bony malignant tumors and up to 5% of all osteosarcomas. In this article, we report a rare case of parosteal osteosarcoma of the mandible on computed tomography (CT) and magnetic resonance imaging (MRI) findings. We showed the tumor arose at the periphery of the bone by CT and MRI. These findings can be helpful for differentiating parosteal osteosarcoma from other tumors of the mandible.
