[Apical pulmonary fibrosis in the course of ankylosing spondyloarthritis]

Two cases of an association between lung TB and ankylosing spondyloarthritis are presented. In the first case, spondyloarthritis appeared about 1 yr after fibrocavitary lesions of the LSD. The literature contains only 1 similar case, in which the gap was two years. In the second case, such lesions appeared 8 yr after spondyloarthritis. Neither patient received radiation treatment. The first received cortisone for massive joint inflammation when typical lung TB lesions were already evident. It is felt that these two additions to the literature are of interest in clarifying the delicate questions of diagnosis that arise when ankylosing spondylarthritis is accompanied by lung involvement.
