Surgery for fibrous dysplasia associated with aneurysmal-bone-cyst-like changes in right proximal femur: A case report

Figure 1 Preoperative radiographic images of fibrous dysplasia associated with aneurysmal-bone-cyst-like changes. A: Preoperative anteroposterior X-ray showed ground-glass appearance with cortical scalloping and expansion of the right proximal femur and femoral neck; B and C: Preoperative computed tomography (CT). Axial CT showed multiseptated proximal femur lesion with a cyst in the right proximal femur and femoral neck (orange asterisk); D-F: Preoperative magnetic resonance imaging (MRI). Coronal and sagittal fat-suppressed, contrast-enhanced T1-weighted MRI of the right proximal femur and femoral showed multiseptated proximal femoral lesion with a dominant cystic cavity without any adjacent soft-tissue edema (black asterisk). Axial fat-suppressed, contrast-enhanced T2-weighted MRI and a sagittal fat-suppressed, contrast-enhanced T1-weighted MRI showed multiseptated proximal femoral lesion with fluid-fluid levels (orange arrows).
