osseous lesions preferentially involving the epiphysis

Epiphyseal lesions comprise tumors and other pathologies that occur around the epiphysis and any epiphyseal equivalent bone.

Differential diagnosis

Common differential diagnoses include the following :

• chondroblastoma: rare epiphyseal tumor found in young adults; it usually does not extend into the metaphysis, and usually does not extend beyond the bone
• giant cell tumor (GCT): occurs in adolescents in whom the epiphyseal growth plates have closed; it can extend to involve the adjacent metaphysis
• geode/intraosseous ganglion
• osteomyelitis
• clear cell chondrosarcoma
• others that occur rarely
  • osteosarcoma and osteoblastoma
  • aneurysmal bone cyst (ABC): usually metaphyseal, but if it occurs after the growth plate is obliterated, it may extend into the epiphysis
  • brown tumor
  • haemophilic pseudotumor
  • enchondroma
  • eosinophilic granuloma
  • osteoid osteoma

The more common of the above entities may be recalled with a mnemonic: epiphyseal lesions (mnemonic).
