Osteosarcoma (OS) is the most common primary bone malignant tumor in which osteoid is produced directly by malignant stroma as opposed to adjacent reactive bone formation. Osteosarcoma of the jaw (OSJ) represent less than 10% of all osteosarcomas and less than 1% of all malignant tumors of the head and neck. The dentist may be the first health care professional who observes tumors involving the jaws. Early diagnosis and radical surgery are the keys to high survival rates.
Conventional radiographs are of limited value in head and neck osteosarcomas because of the superimposed bony structures. CT provides excellent detection of tumor calcification, cortical involvement, and, in most instances, soft-tissue and intramedullary extension. MR is even more effective in demonstrating the intramedullary and extra osseous tumor components on both T1- and T2-weighted images thus helps not only in better preoperative assessment but also post operative follow up. Hereby, reporting a case of osteosarcoma of mandible in a 40 year old female patient with emphasis on CT and MR imaging characteristics.
