Diffuse bubble sclerotic and ground glass change involving the proximal and mid-tibial diaphysis with expansion of the medullary cavity, in keeping with known fibrous dysplasia.
A large, bubbly, lytic lesion with mild ground-glass change, up to 9.5 cm in diameter, involving the left iliac wing, is also in keeping with fibrous dysplasia.
Internal fixation of the left femur with and intramedullary nail and proximal and distal cross-bolts is unchanged, transfixing the now healed left femoral mid-shaft fracture.
Conclusion: Changes of polyostotic fibrous dysplasia, as described, predominantly involving the left side (left iliac wing, femur and tibia).
