Is fibrous cortical defect painful?

The fibrous cortical defect is seen as a small radiolucent defect in the metaphyseal cortex, in close proximity to the growth plate. They have asymptomatic, self-limited natural history. Lesions may be asymptomatic. However, as they grow, they may become painful or undergo pathologic fracture.

Is fibrous cortical defect treatment?

Most will require no treatment, as the nonossifying fibroma will resolve on its own when the child is fully grown. Nonossifying fibromas are also known as fibrous cortical defects and cortical desmoids.

What is the most common location for a fibrous cortical defect?

The lesions were most commonly located within the knee joint (proximal tibia n=9, distal femur n=7) and in distal tibia (n=7). Other locations were less frequent (proximal femur n=2, one case of a lesion in femoral shaft, one in proximal humerus, and one in proximal fibula).

What is a Nonossifying fibroma?

A non-ossifying fibroma is a benign (non-cancerous), non-aggressive tumor that consists mainly of fibrous tissue. It usually occurs in the thighbone or shinbone but may also occur in the upper extremities. A non-ossifying fibroma usually produces no symptoms.

Can non ossifying fibroma cause pain?

NOFs generally do not cause any symptoms. It is rare for an NOF to cause pain or lead to a mass that you can feel. A few patients may have mild pain, especially with activity. This usually is due to a small fracture (break in the bone) that occurs if the NOF is large, which can weaken the bone.

What is cortical irregularity definition?

Assoc Prof Craig Hacking ◉ ◈ and Dr David Dang et al. Cortical desmoids, also known as cortical avulsive injuries, Bufkin lesion or distal femoral cortical defects/irregularities, are a benign self-limiting entity that are common incidental findings.

What happens to the bones in fibrous dysplasia?

Fibrous dysplasia is a condition that causes abnormal growth or swelling of bone. The affected bone becomes enlarged, brittle and warped. Fibrous dysplasia can occur in any part of the skeleton but the bones of the skull and face, thigh, shin, ribs, upper arm and pelvis are most commonly affected.

What is Osteoblastoma?

Osteoblastoma is a slow-growing tumor that dissolves normal, healthy bone and makes a new type of abnormal bone material called osteoid. This osteoid bone material builds up around normal bone. Because the osteoid bone is weaker than normal bone, the area surrounding the tumor becomes more vulnerable to fracture.

Can a non ossifying fibroma cause pain?

Do non cancerous tumors hurt?

Benign tumors may be large enough to detect, particularly if they’re close to the skin. However, most aren’t large enough to cause discomfort or pain. They can be removed if they are.

Can a benign bone tumor turn cancerous?

Certain benign tumors can spread or become cancerous (metastasize). Sometimes your doctor may recommend removing the tumor (excision) or using other treatment techniques to reduce the risk of fracture and disability. Some tumors may come back–even repeatedly–after appropriate treatment.

Is there such a thing as a fibrous cortical defect?

Fibrous cortical defects (FCD) are benign bony lesions and are a type of fibroxanthoma, histologically identical to the larger non-ossifying fibroma (NOF).

How does a non ossifying fibroma look on MRI?

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.

Can a benign tumor be a fibrous lesion?

The lesion simulates a fibrous cortical defect, except in the specificity of its location. Occasionally, it may simulate an aggressive and even malignant tumor.

How often do you need a radiograph for a cortical defect?

Patients with typical lesions require only one follow-up examination with radiograph 6-12 weeks from diagnosis. A fibrous cortical defect usually ossifies at puberty. However, patients with large lesions must be followed every 4-6 months to evaluate progression of lesion size.
