Lytic Bone Lesion Mnemonic – FEGNOMASHIC

This is a commonly used mnemonic to recall the differential diagnosis of lytic bone lesions: F – fibrous dysplasia, fibrous cortical defect E – enchondroma (of the tibia here or of a phalanx here), eosinophilic granuloma G – giant cell tumor N – non-ossifying fibroma O – osteoblastoma M – metastases, myeloma A – aneurysmal…

This is a commonly used mnemonic to recall the differential diagnosis of lytic bone lesions:

F – fibrous dysplasia, fibrous cortical defect
E – enchondroma (of the tibia here or of a phalanx here), eosinophilic granuloma
G – giant cell tumor
N – non-ossifying fibroma
O – osteoblastoma
M – metastases, myeloma
A – aneurysmal bone cyst
S – solitary bone cyst (unicameral bone cyst)
H – hyperparathyroidism
I – infection (osteomyelitis)
C – chondroblastoma and chondromyxoid fibroma
