Thoracic spinal osteochondroma: A rare presentation of spinal cord compression

Osteochondromas are the most common benign bone tumor typically seen in the appendicular skeleton and are rarely found in the spine. We present a case of an osteochondroma of the spine presenting with spinal cord compression. 27-year-old male presented with lower extremity weakness and paresthesia, decreased lower extremity sensation, and decreased proprioception. MRI showed a heterogeneous mass with minimal peripheral enhancement and without restricted diffusion. CT demonstrated a calcified mass extending from the left facet joint of T11-T12 with medial extension, resulting in severe central canal stenosis and cord compression. The patient underwent surgical resection with pathology demonstrating an osteochondroma.
