  • Figure 1
    Axial CT scans of the mandibular region
     

    Axial CT scans with soft tissue window settings at the same level show an extensive mandibular lesion extending throughout the masticator space and compressing the parapharyngeal space. The perpendicular spiculated...

     
    Area of Interest: unknown; Imaging Technique: Axial CT scans of the mandibular region;

    The perpendicular spiculated periosteal reaction is demonstrated to the best on the images with bone window setting.

Gd-enhanced SE T1-weighted MR image demonstrating a low intensity, irregular lesion that enhances after gadolinium administration. The borders of the lesion, the infiltrative intramedullary extension and the spiculated pattern of new bone formation are particularly well demonstrated.
