Figure 11. (a) (Case 12) Radiograph shows an expansile lesion in the right femur involving the lesser trochanter and the proximal shaft. (b) (Case 12) Radiograph, taken 1 year after open surgical curettage and treatment with bone grafting, shows multiple radiodense areas within the lesion corresponding to the areas of bone graft. (c) (Case 12) Coronal T1 weighted image shows a heterogeneous appearance of the lesion, which is predominantly isointense to skeletal muscle, with multiple hypointense foci. A few small hyperintense areas are also seen within it. (d) (Case 12) Coronal contrast-enhanced fat-suppressed T1 weighted image shows multiple areas of enhancement at the periphery of the lesion.
