Updates to Article Attributes
Body
was changed:
Epiphyseal lesions comprise of tumours and other pathologies that occur around the epiphysis and any epiphyseal equivalent bone.
Differential diagnosis
Common differential diagnoses include 2-4:
-
chondroblastoma: rare epiphyseal tumour found in young adults; it usually does not
usuallyextend into the metaphysis, and usually does notusually have extensionextend beyond the bone -
giant cell tumour (GCT): occurs in
older childhood andadolescents in whom the epiphyseal growth platesarehave 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
then, it may extend into the epiphysis - brown tumour
- haemophilic pseudotumour
- enchondroma
