    Computed tomography (CT) effectively visualizes rare mandibular osteosarcomas, detailing bone destruction and formation. CT precisely maps tumor extent, crucial for surgical and radiotherapy planning in these uncommon jaw cancers.

    Area of Science:

    • Oncology
    • Radiology
    • Medical Imaging

    Background:

    • Osteosarcoma of the mandible is an exceptionally rare malignancy.
    • Accurate diagnosis and staging are critical for effective treatment planning.

    Observation:

    • Computed tomography (CT) was utilized to examine two cases of mandibular osteosarcoma.
    • CT demonstrated excellent visualization of osteolytic, osteoblastic, and extra-osseous tumor components.

    Findings:

    • The attenuation coefficient of calcified and non-calcified osteoid varied significantly, ranging from +19 to +320 EMI units.
    • CT precisely defined the extension of lesions into adjacent anatomical structures, including the pterygopalatine fossa, infratemporal fossa, and cranial cavity.

    Implications:
