An osteochondroma is characterized by an osseous component capped by cartilage and is connected to bone by a stalk . Spinal osteochondroma comprises only 3% of solitary osteochondroma but may cause spinal cord compression [4, 5, 6].

Although several case reports have described paraarticular osteochondromas, all of the lesions reported were adjacent to the joints of the extremities, most of which involved the knee region [3, 8].
