Osteoblastoma. Axial (a) CT image of the thoracic spine demonstrates a lytic lesion involving the T7 vertebral body (orange arrow) and posterior elements, with an expansile soft tissue component. A thin sclerotic rim can be seen along the border of the intervertebral portion of the lesion (white and black arrows). Sagittal T2 (b), T1 pre-contrast (c), and T1 post-contrast (d) MR images again demonstrate a lesion involving the T7 vertebral body and posterior elements (orange arrows), as well as invasion of the adjacent paraspinal soft tissues. The lesion is predominantly low to intermediate signal compared to normal marrow, and demonstrates avid enhancement on post-contrast images
