  • Figure 1
    Lytic lesion of the right femoral head

    Frontal radiograph of the pelvis shows a well-circumscribed lytic lesion in the right femoral head, with central matrix calcification.

     
    Area of Interest: unknown; Imaging Technique: Lytic lesion of the right femoral head;
     
     
  • Figure 2
    CT

    Transverse 3mm thick CT scan of the right femoral head shows to better advantage the well-defined sclerotic rim of the lesion and the central calcification.

     
    Area of Interest: unknown; Imaging Technique: CT;

    MR imaging
     

    A coronal T1-weighted spin-echo image shows the low signal intensity lesion in the right femoral head. The spherical contour of the head is intact.

     
    Area of Interest: unknown; Imaging Technique: MR imaging;

    A coronal T2-weighted fat-suppressed turbo-spin-echo image shows the low signal intensity central calcified matrix of the lesion, the high signal intensity halo corresponding to the non-mineralised matrix and a...

     
    Area of Interest: unknown; Imaging Technique: MR imaging;

    Oblique fat-suppressed contrast-enhanced T1-weighted spin-echo image demonstrates intense enhancement in the non-mineralised portions of the lesion.

     
    Area of Interest: unknown; Imaging Technique: MR imaging;
     
     
  • Figure 4
    Gross specimen

    Macroscopic view of the excised femoral head shows the central calcified matrix and the peripheral non-calcified tumoral tissue.
