Fibrous dysplasia in tibia

Discussion:

Fibrous dysplasia is a skeletal developmental anomaly of the bone-forming mesenchyme that manifests as a defect in osteoblastic differentiation and maturation. Virtually any bone in the body can be affected. It is a nonhereditary disorder of unknown cause.

In this case the diagnosis is straightforward as typical features are present. X-ray is still the examination of first choice. For postoperative follow-up, gadolinium-enhanced MRI can be useful in demonstrating the proliferation of fibrocellular tissue.
