What is focal cortical defect?

FCDs are benign lytic bone lesions, and, along with fibrous dysplasia share the F in the popular mnemonic FEGNOMASHIC. They typically occur in the metaphysis or diametaphyseal junction and appear as small (<2-3 cm) lucent defects within the cortex that over time become sclerotic as they heal.

How would you describe non-ossifying 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.

What are cortical defects?

To begin with, the fibrous cortical defect is a benign fibrous tumour occurring, in the cortex of the metaphysis, only in the long bones of children and young adolescents. The term “fibrous cortical defects” has been given, as these lesions are composed of fibrous tissue.

What is a fibrous cortical lesion?

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

What is a renal cortical defect?

Renal (kidney) cortical necrosis is death of the tissue in the outer part of the kidney (cortex) that results from blockage of the small arteries that supply blood to the cortex and that causes acute kidney injury. Usually the cause is a major, catastrophic disorder that decreases blood pressure.

What is a benign Fibroxanthoma?

Fibroxanthoma (Nonossifying Fibroma) ○ One of most common benign bone lesions of children and teenagers. ○ Metaphysis is most common location (may become metadiaphyseal with continued growth of child) ○ Usually eccentric (or cortically based, appearing eccentric)

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 does FCD mean in medical terms?

Fibrous cortical defects (FCD) are benign bony lesions and are a type of fibroxanthoma, histologically identical to the larger non-ossifying fibroma (NOF). Fibrous cortical defects macroscopically appear as fleshy, fibrous, yellow or tan-brown lesions with variable areas of haemorrhage 3.

What are fibrous cortical defects (FCD)?

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

What is an FCD lesion in the brain?

FCDs are benign lytic bone lesions, and, along with fibrous dysplasia share the F in the popular mnemonic FEGNOMASHIC. They typically occur in the metaphysis or diametaphyseal junction and appear as small (<2-3 cm) lucent defects within the cortex that over time become sclerotic as they heal.

What does Nof stand for?

Author: Bernardo Vargas, MD; Chief Editor: Omohodion (Odion) Binitie, MD more… Fibrous cortical defect (FCD; also referred to as nonossifying fibroma [NOF] or nonosteogenic fibroma) was first described by Phemister in 1929.
