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

Abstract

Case report and review of the literature. 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. Osteochondroma is the most common benign lesion of bone but rarely affects the spine. Clinical history, routine radiographs, and computed tomography study of the patient were described. A review of the relevant literature was also done. 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. 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.
