Chronic obstructive pneumonia caused by a vertebral body osteophyte.

Osteophytes associated with spondylosis have been implicated as a cause of multiple extraspinal manifestations. Symptoms are more likely to occur with the large osteophytes associated with diffuse idiopathic skeletal hyperostosis. In the thoracic region, osteophytes have been reported infrequently as a cause of extraspinal complications. We report a case in which an anterior thoracic vertebral osteophyte was responsible for chronic obstructive pneumonia due to obstruction of the right main stem bronchus. The patient's condition improved considerably after surgical resection of the compressing thoracic osteophyte.
