title: Pulmonary manifestations of ankylosing spondylitis.
abstract: Chest radiographs of 39 patients with ankylosing spondylitis were studied. Three showed apical pulmonary fibrosis, two with cavitary lesions. Other known causes of lung disease were excluded. Symptoms and roentgenographic evidence of spondylitis were present for many years prior to the onset of pulmonary symptoms, which variably included shortness of breath, cough, hemoptysis, pleuritic chest pain, fever, and chills. Apical pulmonary lesions of unknown cause were absent in 53 age, sex, and racematched osteoarthritis control patients. The findings suggest that apical pulmonary fibrosis may be an extra-skeletal manifestation of ankylosing spondylitis, the frequency of which approaches that of spondylitic heart disease.
