female, 7 year(s)
 
 
  • Figure 1
    Panoramic radiograph

    Unicystic radiolucency and extensive destruction of the right mandibular ramus

     
    Area of Interest: unknown; Imaging Technique: Panoramic radiograph;
     
     
  • Figure 2
    CT-scan
     

    Axial CT scan.Lytic radiolucency, aggressive expansile balooning lesion with cortical destruction and presence of internal trabeculation.

     
    Area of Interest: unknown; Imaging Technique: CT-scan;

    Axial CT scan: subperiostal reaction

     

    Coronal MPR reformat:lesion of the right mandible ramus with cortical expansion and perforation.

     
    Area of Interest: unknown; Imaging Technique: CT-scan;

    3D CT reconstruction: expanded, moth eaten right mandibular ramus caused by extensive and destructive lesion.

     
    Area of Interest: unknown; Imaging Technique: CT-scan;

    MRI
     

    Axial FSE T2-weighted MR image with fat saturation shows high signal intensity of the expansile ballooning lesion with hypointense septations in betwen them.

     
    Area of Interest: unknown; Imaging Technique: MRI;

    Axial SE T1-weighted MR image shows low intensity expansile ballooning lesion.

     
    Area of Interest: unknown; Imaging Technique: MRI;

    Axial SE T1-weighted MR image shows low intensity expansile ballooning lesion with enhancement of septation in between them.

     
    Area of Interest: unknown; Imaging Technique: MRI;

    Follow-up

    The follow-up showed stability of the lesion and condensation of the border.
