  • Figure 1
    Orthopantomogram
     

    A well-defined lucent lesion is present in the right angle of the mandible. It has a narrow zone of transition and a sclerotic margin and is sited below the mandibular canal, indicating a non-odontogenic origin.

     
    Area of Interest: unknown; Imaging Technique: Orthopantomogram;

    Enlarged view of the orthopantomogram. The abnormality has all the hallmarks of a benign lesion.
