Horner Syndrome due to a solitary osteochondroma of C7: a case report and review of the literature.

STUDY

DESIGN

Case report and review of the literature.

OBJECTIVE

To report a 23-year-old woman with osteochondroma of the lower cervical spine who presented with Horner syndrome and to review the relevant literature.

SUMMARY OF BACKGROUND DATA: Osteochondroma is the most common benign lesion of bone but rarely affects the spine.

METHODS

Clinical history, routine radiographs, and computed tomography study of the patient were described. A review of the relevant literature was also done.

RESULTS

The patient demonstrated a complete disappearance of clinical symptoms on the follow-up examination 60 days after surgery. No patients with Horner syndrome due to a solitary cervical osteochondroma have been previously reported in English-language medical literature.

CONCLUSION

Vertebral involvement of osteochondroma is rare, especially with neurologic compromise. A young patient is presented with a symptomatic solitary osteochondroma of the seventh cervical vertebra who had Horner syndrome. This case report supports surgical intervention of symptomatic osteochondroma of the cervical spine.
