Patient
male, 18 year(s)
 
 
  • Figure 1
    A conventional X-ray of the left ankle

    An X-ray image showing an osteolytic lesion of the talar neck (indicated by an arrow).

     
    Area of Interest: unknown; Imaging Technique: conventional X ray of the left ankle;
     
     
  • Figure 2
    Ultrasonography, sagittal view of the left ankle

    A sagittal ultrasonogram showing intra-articular fluid suffusion (indicated by an arrow) with synovial thickening (indicated by an arrowhead).

     
    Area of Interest: unknown; Imaging Technique: Ultrasonography, Sagittal view of the left ankle;
     
     
  • Figure 3
    Sagittal MRI slices of the left ankle
     

    A sagittal T1-weighted MRI study showing a focal lesion of the talar neck surrounded by a marginal osteosclerosis and perilesional edema and inflammation.

     
    Area of Interest: unknown; Imaging Technique: Sagittal MRI slices of the left ankle;

    A sagittal T2-weighted MRI study showing a moderate intra-articular fluid suffusion. The nidus shows a central area of low signal and a peripheral marginal osteosclerosis.

     
    Area of Interest: unknown; Imaging Technique: Sagittal MRI slices of the left ankle;

    A post-contrast sagittal T1-weighted MRI showing a moderate enhancement of the nidus (indicated by an arrow) associated with a synovial gadolinium-hold (indicated by an arrowhead).

     
    Area of Interest: unknown; Imaging Technique: Sagittal MRI slices of the left ankle;
     
     
  • Figure 4
    A sagittal CT reconstruction

    A subperiosteal lytic lesion with a partially calcified central nidus surrounded by a marginal osteosclerosis.
