Discussion of Osteofibrous dysplasia
- Osteofibrous dysplasia is sometimes referred to as ossifying fibroma. The latter term is discouraged, as it refers also to an unrelated lesion of the mandible.
- Osteofibrous dysplasia involves the tibia in approximately 90% of cases.
- The lesions are usually diaphyseal, especially involving the middle to distal third of the shaft and typically involving the anterior cortex.
- Patients present in the 1st or 2nd decade.
- Distinction between fibrous dysplasia, adamantinoma, and osteofibrous dysplasia can be difficult.
- Controversy does exist as to the possibility that osteofibrous dysplasia is in essence an early adamantinoma or is prone to transformation.
- Contemporary theory would consider the two as distinct entities.
- It has been suggested that osteofibrous dysplasia has a more favorable prognosis than either fibrous dysplasia or adamantinoma, as it exhibits a tendency toward spontaneous regression without residual skeletal deformity
 Imaging Findings for Osteofibrous dysplasia
- Diaphyseal lesion, especially involving the middle to distal third of the shaft and typically involving the anterior cortex.
- Bowing and enlargement of the bone are typically seen, often with a characteristic adjacent sclerotic band
