How is non-ossifying fibroma treated?

Non-ossifying fibromas are removed through a simple surgical procedure called curettage. Surgeons scrape the tumor out of the bone with special tools. Then they’ll fill in the hole with a bone graft, either from your child’s own body or from a bone donor. Sometimes they may use a bone replacement material.

What causes a non-ossifying fibroma?

Its cause is unknown. It’s often discovered by chance on an X-ray. Surgery is only necessary of it causes a fracture or weakens the bone.

Can non-ossifying fibroma be cancerous?

Non-ossifying Fibroma (NOF) is the most common bone tumor in kids. It may occur in 35% of all children. It is not cancer. NOF is benign, which means it is just a collection of abnormal cells that stays where it is and does not move to other parts of the body.

Are lucent lesions cancerous?

Lucent lesions of the sternum should be considered malignant until proven otherwise (Helms CA, personal communication, 1983). Keep in mind that the classic descriptions of bone tumors that you spend so much time studying are for untreated lesions.

What can cause lucency of the bone?

Differential Diagnosis of Solitary Lucent Bone Lesions

• Fibrous Dysplasia.
• Osteoblastoma.
• Giant Cell Tumor.
• Metastasis / Myeloma.
• Aneurysmal Bone Cyst.
• Chondroblastoma / Chondromyxoid Fibroma.
• Hyperparathyroidism (brown tumors) / Hemangioma.
• Infection.

Are bone islands serious?

Bone islands are typically not dangerous. They’re not cancerous, and rarely cause any symptoms.

Can osteoblastoma become malignant?

Although osteoblastoma is considered a benign tumor, there have been very rare cases in which an osteoblastoma has transformed into a malignant (cancerous) tumor.

What is a non ossifying fibroma?

Non-ossifying fibroma is one of the skeletal “Don’t touch” lesions. Most non-ossifying fibromas require no treatment or biopsy. If large (involving more than 50% of the diameter of the parent bone) then prophylactic curettage and bone grafting may be prudent to avoid a pathological fracture 1.

What are the possible complications of non-ossifying fibromas?

Larger lesions may be painful and potentially weaken the bone enough to predispose to pathological fracture. Multiple non-ossifying fibromas are associated with neurofibromatosis type 1 (NF1) and Jaffe-Campanacci syndrome .

What are the treatment options for non-ossifying fibroma?

Most non-ossifying fibromas require no treatment or biopsy. If large (involving more than 50% of the diameter of the parent bone) then prophylactic curettage and bone grafting may be prudent to avoid a pathological fracture 1.

Which MRI findings are characteristic of non-ossifying fibromas?

MRI appearances of non-ossifying fibromas are variable and depend on when along with the development and healing phase the lesion is imaged. Initially, the lesion has a high or intermediate T2 signal, with a peripheral low signal rim corresponding to the sclerotic border.
