Figure 10. (a) (Case 9) Anteroposterior radiograph shows an osteolytic lesion in the medial aspect of the proximal end of the tibia with a thin sclerotic rim. There is a large area of calcification in the central region. (b) (Case 9) Coronal contrast-enhanced fat-suppressed T1 weighted image shows patchy central enhancement and a peripheral enhancing rim. There is a non-enhancing hypointense area corresponding to the calcification on the radiograph. In addition, there is a focal extension of the lesion through the medial cortex. (c) (Case 9) Axial contrast-enhanced fat-suppressed T1 weighted image confirms a break through the medial cortex at the level of the enhancing lesion, consistent with a pathological fracture.
