case_images: Non-contrast (images A, B, and C) and contrast (image D) magnetic resonance imaging revealed a tumorous lesion at the level of the D6 and D7 vertebrae, measuring about 4 cm x 4 cm x 5 cm. The lesion showed high signal intensity on T2-weighted images, low signal intensity on T1-weighted images, and heterogeneous enhancement post-contrast image, with erotion of the D6 posterior arch and the right pedicle, causing spinal cord compression. (A: Sagittal section of T1-weighted sequence, B: Axial section of T2-weighted sequence, C: Sagittal section of T2-weighted sequence, D: Sagittal section of T1-weighted sequence).

case_images: The lesion showed high signal intensity on T2-weighted images, low signal intensity on T1-weighted images, and heterogeneous enhancement post-contrast image, with erotion of the D6 posterior arch and the right pedicle, causing spinal cord compression. [Fig. 1].
case_images: Intraoperative images demonstrate that the lesion eroded the right lamina, facet joint, and rib junction (image B). Following complete tumor resection, a defect in the vertebral body was visibled, with the spinal cord having been relieved from compression (image A).

case_images: A neurosurgery specialist performed tumor resection, revealing the mass to be fragile, bleeding, and highly vascularized from a subcostal artery, eroding the bone [Fig. 2].
case_images: Anteroposterior (image B) and lateral (image A) X-rays of the thoracic spine reveal a transpedicular fixation device comprising eight pedicle screws at T5, T6, T8, and T9 levels, along with connectors and four rods. Lateral mass screws were utilized due to the unavailability of pediatric devices.

case_images: Spinal stabilization was achieved using eight pedicle screws, rods, and a bridge, with cervical screws employed due to the unavailability of pediatric screws [Fig. 3].
case_images: Histological examination showed bone trabecula and a tumor comprised mainly of multinucleated giant osteoclasts and spindle-shaped mononuclear macrophage-like cells. The stroma contains blood vessels and diffuse hemorrhagic regions, with no signs of sarcomatous change.
