Localized Bronchiectasis Secondary to an Allergic Response Provoked by Vertebral Osteophytes.

Thoracic vertebral osteophytes have been reported to affect the adjacent organs. We report an uncommon case of localized bronchiectasis secondary to an allergic reaction stimulated by vertebral osteophytes. A man in his 60s presented with a 2.5-cm lung nodule connected to the proximal segmental bronchus in the right lower lobe near vertebral osteophytes that caused obstructive pneumonia due to mucoid impaction. His medical history suggested a tendency for development of allergic respiratory tract reactions. Thoracoscopic resection was successfully performed, and histopathologic examination confirmed the pathogenesis.
