Epiphyseal lesions (mnemonic)
Updates to Article Attributes
Body
was changed:
The differential diagnosis for epiphyseal lesions can be recalled with mnemonics for the most common entities:
- Chondroblastoma IS AGE-related 1
See the separate article for the full list: epiphyseal lesions (differential)/osseous lesions preferentially involving the epiphysis.
Mnemonics
Chondroblastoma IS AGE-related
This mnemonic notes the fact that the appropriate differential changes with the age of the patient, with chondroblastoma being the most common primary neoplasm in this region in children.
- Chondroblastoma and other chondrogenic tumors (enchondroma, clear cell chondrosarcoma)
- I: infection (osteomyelitis)
- S: subchondral cyst/cystlike lesion (geode)
- A:avascular necrosis (subchondral osteonecrosis) and osteochondral lesions (e.g., osteochondritis dissecans)
- G: giant cell tumor
- E: eosinophilic granuloma
An alternative is the following 1:
- Chondroblastoma
- I: infection or infarction
- S: solitary/simple bone cyst
- A: aneurysmal bone cyst
- G: giant cell tumor or geode
- E: enchondroma or eosinophilic granuloma
