Overview
On x-ray, fibroma is characterized by sharply demarcated, asymmetrical, cortically based lucencies with a thin sclerotic rim.
X-Ray
Non-ossifying Fibroma
- On X-Ray, non-ossifying fibromas are characterized by sharply demarcated, asymmetrical, cortically based lucencies with a thin sclerotic rim.
- They often appear multiloculated. They are located in the metaphysis, adjacent to the physis. As the patient ages, they seem to migrate away from the growth plate.
- They have no associated periosteal reaction, cortical breach or associated soft tissue mass.
Ossifying Fibroma
The following radiographic features are noted on x-ray of ossifying fibroma:
- Ossifying fibroma is seen as a well-circumscribed lesion
- Ossifying fibroma demonstrates evidence of intracortical osteolysis with a characteristic sclerotic band
- Cortical expansion
Chondromyxoid Fibroma
The following features are seen on plain radiograph of chondromyxoid fibromas:
- Chondromyxoid fibroma is seen as a lobulated, eccentric radiolucent lesion
- Long axis is parallel to long axis of long bone
- No periosteal reaction (unless a complicating fracture present)
- In approximately 100% of cases geographic bone destruction is present
- In approximately 85% of cases well defined sclerotic margin is present
- In approximately 60% of cases there can be presence of septations (pseudotrabeculation)
- In approximately 12.5% there can be presence of matrix calcification
