monostotic fibrous dysplasia

Thân thiện

A patient's X-ray shows a single bone affected by monostotic fibrous dysplasia.

Definition

Noun: A benign bone condition characterized by the abnormal development of fibrous tissue within the bone marrow, replacing normal bone. This condition affects only a single bone in the body.

Usage

The term is used in medical contexts to describe a specific, localized form of fibrous dysplasia. It is a diagnostic classification.

Examples

• The X-ray revealed a lesion consistent with monostotic fibrous dysplasia in the patient's femur.
• Unlike the polyostotic form, monostotic fibrous dysplasia is typically found in a single rib or long bone.
• Treatment for monostotic fibrous dysplasia is often conservative unless the lesion causes pain or a risk of fracture.

Advanced Usage

• The term is often contrasted with , which affects multiple bones.
• It may be part of a differential diagnosis when a solitary bone lesion is discovered on imaging.

Variants and Related Words

• Fibrous dysplasia (n): The broader category of the disorder, which can be monostotic (single bone) or polyostotic (multiple bones).
• Polyostotic fibrous dysplasia (n): The form of the disease that involves multiple bones.

Synonyms

• Solitary fibrous dysplasia
• Localized fibrous dysplasia

Notes on Meaning

The condition itself is the same pathological process as polyostotic fibrous dysplasia; the prefix "monostotic" specifies the extent (one bone) rather than indicating a different disease.
