male, 27 year(s)
 
 
  • Figure 1
    Conventional radiography

    Subtle erosion and discrete scaffolding of the cortex of intermediate and lateral cuneiform bone is seen.

     
     
     
  • Figure 2
    MR examination
     

    Transverse T2 STIR sequence demonstrates the nidus with dot-like central calcification (arrow), and the surrounding soft tissue edema.

     

    Sagittal T2 STIR image demonstrates the nidus (arrow).

     

    Coronal T2 sequence demonstrates the nidus (arrow), adjacent to the intermediate cuneiform bone.

     
     
     
  • Figure 3
    CT examination
     

    Axial CT image demonstrates the nidus (arrow) as a hypodense lesion with a central dot-like calcification.

     

    Sagittal CT image demonstrates scaffolding of the cortex of cuneiform bones (arrow).

     

    Coronal CT image demonstrates scaffolding of the cortex of cuneiform bones (arrow).

     
     
     
  • Figure 4
    Laser photocoagulation
     

    Coronal CT image during CT-guided percutaneous laser photocoagulation demonstrates position of the needle tip in the nidus of the lesion.

     

    Sagittal CT image during CT-guided percutaneous laser photocoagulation demonstrates position of the needle tip (arrow) in the nidus of the lesion.
