Vertebra plana (plural: vertebrae planae), also known as the pancake, silver dollar or coin-on-edge vertebra, is the term given when a vertebral body has lost almost its entire height anteriorly and posteriorly, representing a very advanced compression fracture.
Pathology
It can occur in a variety of settings, including:
-
Langerhans cell histiocytosis (LCH)
most common cause of vertebra plana in children
-
most common primary pediatric malignancy
loss of vertebral height and increased sclerosis are common in the vertebral body
-
B-symptoms and multiple levels involvement unlike LCH, which commonly involves a single level
-
bacterial infection commonly causes disc destruction and vertebral
body endplate erosionsspinal tuberculosis spondylitis commonly causes bone destruction with somewhat relative disc preservation, which can cause vertebra plana, however, some form of vertebral endplate change is usually present
chronic recurrent multifocal osteomyelitis: rare cause in children 3
In pediatric population, vertebra plana is generally due to:
There are a number of mnemonics for the causes of vertebra plana.
