Breast cancer is one of the most common types of neoplasm causing vertebral metastases. The infiltrated vertebrae are prone to pathological fractures. Although there is fluid sign present in the T12 collapsed vertebral body, which is rather typical for osteoporotic fractures, other features like bone marrow replacement with involvement of the pedicles, posterior cortex bulging and other vertebral metastases strongly favor a pathological vertebral fracture.
