Record 1 2012-02-20

English

Subject field(s)
  • Radiography (Medicine)
  • Musculoskeletal System
DEF

A small deposit of subperiosteal bone at the periphery of a bone tumor or infection. Radiologically this produces a triangular appearance on the surface of the bone at the edge of the lesion. The appearance is mainly seen in sarcoma of bone, although it may be seen in osteomyelitis. [From BUMED, 1989, p. 383 and GOMED, 1979, p. 292.]

DEF

Apposition périostée en forme de petit triangle, résultant du soulèvement du périoste en périphérie d’une lésion tumorale ou infectieuse de l’os. Bien qu’on l’observe habituellement en relation avec un ostéosarcome, il se rencontre également dans l’ostéomyélite. [D’après TRIAR, 1974, volume 3, pp. 24, 123.]

  • Musculoskeletal System
CONT

Periosteal reaction refers to the deposition of new bone beneath the periosteum. Several types of reaction may be induced, each with a different dynamic and physiologic implication. The reactions may be unilaminar (single layer), multilaminar, cuffed (Codman's triangle), spiculated, or cloaked.

OBS

The term periostitis is often used loosely in describing non-inflammatory periosteal bone formation; the term periosteal reaction should be employed in such conditions.

  • Appareil locomoteur (Médecine)
DEF

Réaction du périoste vis-à-vis d’une agression locale, se manifestant par une activité ostéogénique. Les appositions périostées sont de plusieurs types : lamellaire, parallèle à la corticale osseuse; spéculaire, perpendiculaire à la corticale osseuse; en éperon. Elles peuvent se voir au cours d’une grande variété de lésions(tumorales; traumatiques; inflammatoires, infectieuses ou non).
