Cervical Spine Myelopathy from Metalloma Association with Chronic Retention of a Bullet

Abstract

A Civilian gunshot wound associated with metallosis in the cervical spine region was an extremely rare case; hence, the clinician had difficulty with diagnosis and surgical treatment. A 57–year-old gentleman had a history of a gunshot wound injury going back 30 years. He presented with neck pain, progress of paresthesia of upper extremities and progressively difficult ambulation for 3 months. Radiographic and pathological diagnosis from tissue of the 7th paravertebral of the cervical spine showed foreign bodies consistent with metallosis. The patient showed improvement of symptoms after posterior cervical spine fixation and decompression. He had full recovery at 1 year follow up. Metallosis can occur in cases of chronic exposure to lead and metals. The results of this chronic process of metallosis will develop to metalloma, which then compresses the spinal cord and develops into myelopathy. The patient had a bullet, or piece of metal at the cervical spine, so surgical removal was performed to prevent further compression of the spinal cord from metalloma.
