case_images: Preoperative T2-weighted magnetic resonance imaging in both sagittal (a and b) and axial (c and d) dimensions demonstrating the osteochondroma causing spinal cord compression

case_images: Thoracic magnetic resonance imaging (MRI) showed a large 5.9 cm x 5.0 cm x 5.4 cm mass emanating from the T9-T10 level with severe cord compression [Figure 1], while the CT scan with bone windows confirmed this mass to be osseous in nature, arising from the posterior vertebral body (VB) of T9 vertebra [Figure 2].
case_images: Preoperative noncontrast computed tomographic scan in both axial (a) and sagittal (b) dimensions demonstrating the osteochondroma with significant encroachment within the spinal canal

case_images: Photomicrograph of the osteochondroma (hematoxylin and eosin stain). A cartilaginous cap (black arrowhead) is noted to be covering the trabecular bone (black arrow)

case_images: Pathologically, the lesion was noted to have a cartilaginous cap centered by trabecular bone with endochondral ossification at the bone-cartilage interface [Figure 3].
case_images: Postoperative noncontrast computed tomographic scan in both axial (a) and sagittal (b) dimensions showing gross total resection of the osteochondroma

case_images: A postoperative CT scan obtained while he was still an inpatient showed gross total resection of the tumor as well as appropriate positioning of the hardware [Figure 4].
case_images: A 6-month follow-up magnetic resonance imaging demonstrates no residual or recurrence of disease. Shown here is the T2-weighted sequence in sagittal (a) and axial (b) dimensions as well ash a T1-weighted postcontrast sequence in sagittal (c) and axial (d) dimensions

case_images: On the last follow-up at 6 months, he was neurologically intact with a resolution of his sensory deficits, and a 6-month postoperative MRI showed no tumor recurrence [Figure 5].
