Radiologic Findings
Axial magnetic resonance imaging (MRI) of the thoracic spine reveals a right T6 and T7 paraspinal mass involving the vertebral bodies with cord compression (Fig. 57-1). Angiogram with T6 and T7 intercostal injections showed a neovascular stain and a hypervascular mass (Fig. 57-2).
