Abstract

We report herein the case of an 18-year-old man who underwent endoscopic resection for an osteoid osteoma in the seventh cervical facet joint. The patient had experienced right neck pain for approximately one year, but no neurological abnormalities were noted. Cervical magnetic resonance imaging suggested an osteoid osteoma in the superior articular process of the seventh cervical vertebra. The tumor was resected microendoscopically. Operative time was 1 hour 29 minutes, and blood loss was 5 mL. During the two years since surgery, the patient has remained pain free with no cervical spine instability. We thus propose microendoscopic surgery for osteoid osteoma developing in a posterior element of the cervical spine is a potentially effective operative procedure.

Lateral view (enlarged) of plain radiographs (initial examination). Alignment is good, and no obvious abnormalities are seen. Closer inspection, however, reveals indistinct lucency of the bone in the right C6/7 facet joint (arrows).

Cervical spine computed tomography. Bone lucency, thought to be a nidus, is seen in the right superior articular process of C7 (arrows).

Axial view of cervical contrast magnetic resonance imaging. There is intensity change (arrows) in the right superior articular process of C7, and a conspicuous contrast effect is seen at the surrounding tissue.
