Patient
male, 40 year(s)
 
 
  • Figure 1
    Film x-ray right leg AP/Lateral

    AP/L X-ray show a lucent area within the proximal tibia with a thick sclerotic rim. Findings in keeping with a well-defined benign appearing osteolytic bone lesion.

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: Percutaneous; Procedure: Education; Special Focus: Tissue characterisation;
     
     
  • Figure 2
    Sagittal oblique CT. Soft tissue (1) and bone(2) filter applied

    Centric bone lesion with predominant low attenuation of dense fluid enclosed by a sclerotic margin (yellow arrow) and a rim of fat density tissue (red arrows), mild bone expansion without disrupting the cortex is seen.

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: CT; Procedure: Education; Special Focus: Tissue characterisation;

    a) Axial SE-T1(left)shows an isointense signal intensity lesion relative to soft tissue with a hyperintense rim. Axial PD SPIR-weighted MR image (right) shows a hyperintense fluid centric lesion with hipointense...

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: CT; Procedure: Education; Special Focus: Tissue characterisation;

    b) Sagital PD SPIR weighted image of right leg showing hyperintense signal intensity lesion(arrow)in keeping with fat necrosis and cyst formation associated with fat suppressed margins.
