Enchondroma of the cervical spine in young woman: A rare case report

Enchondroma is a type of benign cartilaginous bone tumor. Enchondroma of the spine is very rare. There are only a few cases of enchondromas located in the lamina of the cervical spine have been reported. Therefore, we report a case of enchondroma in the cervical spine. A 24-year-old female patient presented with a history of neck pain, restriction of neck movement, pain and numbness along the right scapula, and weakness accompanied by wasting of the right hand. Presumptive diagnoses included bony tumors such as an aneurysmal bone cyst or a giant cell tumor. Radiologic examinations revealed a round tumor in the right lamina of C4 with extracortical extension and foramen of C4-5. C4 right hemilaminectomy and facetectomy were performed with near complete removal of the tumor. On histological examination, the tumor was confirmed to be an enchondroma. At the 6-month follow-up, a computed tomography scan showed no recurrence with good alignment.
