History

This is a case of a 50-year-old male with worsening pain over the past 8 years in both the right upper extremity and right lower extremity. The patient, of note, did not have any neck pain. On clinical examination, there was mild right upper extremity weakness (4/5) and abnormal reflexes in the right upper extremity and right lower extremity. There was mild right lower extremity weakness.

Given the neurologic symptoms, radiographs were obtained, including imaging of the axial skeleton.

Radiologic findings

Multiple imaging studies were obtained. Some of the initial imaging studies obtained were radiographs of the spine. Lateral radiograph of the cervical spine demonstrated a large exostosis involving the posterior elements at the C2-3 level (Fig. 1). Additional radiographs of the chest and spine demonstrated additional sessile osseous exostoses involving the proximal left humerus and right scapula (Figs. 2 and 3). Fig. 1
