Kummel disease is an eponymous name for avascular necrosis of the vertebrae.
It often occurs following a traumatic collapse and risk factors include :
- corticosteroid use
- radiation therapy
Plain film / CT
- shows collapse of affected vertebrae
- an intra-vertebral vacuum cleft may be seen (accentuated on extension stress lateral views), although not a specific feature
- the vacuum cleft is usually seen as low signal intensity with all sequences.
- if intra-vertabral fluid is present 1 it is " low signal on T1 " and " high signal on T2 " weighted sequences.
It was first described by Herman Kummell in 1891 4
