Mnemonics for the differential diagnosis of lucent/lytic bone lesions include:
- FEGNOMASHIC
- FOG MACHINES
They are anagrams of each other and therefore include the same components. They are by no means exhaustive lists, but are a good start for remembering a differential for a lucent/lytic bone lesion and will suffice for >95% of the time .
Mnemonics
FEGNOMASHIC
- F: fibrous dysplasia (FD) or fibrous cortical defect (FCD)
- E: enchondroma or eosinophilic granuloma (EG)
- G: giant cell tumor (GCT) or geode
- N: non-ossifying fibroma (NOF)
- O: osteoblastoma
- M: metastasis(es)/myeloma
- A: aneurysmal bone cyst (ABC)
- S: simple (unicameral) bone cyst
- H: hyperparathyroidism (brown tumor)
- I: infection (osteomyelitis) or infarction (bone infarction)
- C: chondroblastoma or chondromyxoid fibroma
