Vertebral body mass
Broadly, these lesions can be separated into:
- non-neoplastic lesions
- primary bone lesions
- secondary metastatic disease
Primary bone tumors of the spine
Primary bone tumors of the spine are much less common than secondary metastatic disease, and may be benign or malignant.
Secondary metastatic disease
Vertebral metastases are significantly more common than primary bone tumors, especially in an older patient or one with known primary disease elsewhere.
Assessment of whether the bone lesions are sclerotic or lytic may help to narrow the differential diagnosis of primary disease if it is unknown.
