Vertebral body mass

The differential diagnosis for a vertebral body mass is broad and may range from a completely benign, sclerotic enostosis (bone island) to a malignant primary bone tumor.

Broadly, these lesions can be separated into:

non-neoplastic lesions

primary bone tumors

secondary metastatic disease

Non-neoplastic lesions

aneurysmal bone cyst (<2%)

neural arch (60%); vertebral body (40%)

Brown tumor (an osteoclast reaction in hyperparathyroidism)

enostosis

vertebral hemangioma
