She had an en bloc resection, laminectomy of T4, and T3 to T5 posterior instrumented spinal fusion. At the 1-year follow-up, she remained asymptomatic.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Costovertebral osteochondromas are rare and typically discovered once they become symptomatic.
