Lytic bone lesion (mnemonic)

Dr MT Niknejad and Dr Tariq Hakim et al.

Mnemonics for 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 many causes of a lytic bone lesion.

Mnemonics

FEGNOMASHIC

F - fibrous dysplasia OR fibrous cortical defect (FCD)
E - enchondroma OR eosinophilic granuloma (EG)
G - giant cell tumour (GCT)
N - non-ossifying fibroma (NOS)
O - osteoblastoma
M - metastasis(es)
A - aneurysmal bone cyst (ABC)
S - simple (unicameral) bone cyst
H - hyperparathyroidism (brown tumour)
I - infection (osteomyelitis)
C - chondroblastoma OR chondromyxoid fibroma

FOG MACHINES

F - fibrous dysplasia OR fibrous cortical defect (FCD)
O - osteoblastoma
G - giant cell tumour (GCT)
M - metastasis(es)
A - aneurysmal bone cyst (ABC)
C - chondroblastoma OR chondromyxoid fibroma
H - hyperparathyroidism (brown tumour)
I - infection (osteomyelitis)
N - non-ossifying fibroma (NOS)
E - enchondroma OR eosinophilic granuloma (EG)
S - simple (unicameral) bone cyst

It is of course not an exhaustive list (e.g intraosseous lipoma is missing).
