61-year-old man with primary bone angiosarcoma. a Axial CT (bone windows) image shows a destructive lesion centred at the left T9 vertebral body with extra-osseous soft tissue (arrow). b Sagittal T1-weighted image shows low signal change of the T9 vertebral body (arrow) and bulging of the posterior cortex in keeping with malignant infiltration. c Axial T2-weighted image shows infiltration of the T9 vertebral body with a heterogeneous, predominantly high signal intensity left paravertebral mass (arrow) involving the adjacent rib and pleura. There is extra-osseous soft tissue narrowing the spinal canal (arrowheads). d Axial T1 fat-suppressed post-contrast image shows avid heterogeneous enhancement of the T9 vertebral body and the left paravertebral mass (arrow)
