OBJECTIVE: @entity1691 ( @entity1691 ) is a chronic inflammatory disease mainly affecting the axial skeleton and @entity358 is a well known feature of the disease. The aim of this study was to investigate the pulmonary @entity2101 ( @entity2101 ) findings of @entity1 with early @entity1691 . The relationship between pulmonary function tests (PFT) and @entity2101 findings was also determined. SUBJECTS AND METHODS: Twenty-eight @entity1 with @entity1691 (mean age 30.8+/-7.4 and disease duration 7.0+/-2.6) were included in the study. @entity1 with a disease duration of >10 years or had other @entity358 were excluded. All @entity1 underwent plain chest radiography (posteroanterior and lateral views), thoracic @entity2101 and PFT. RESULTS: All chest radiographs were normal and @entity2101 revealed @entity854 @entity1 . The most common abnormalities seen on @entity2101 were mosaic pattern (ten of 28), subpleural nodule (seven of 28) and parenchymal bands (five of 28). Seven of ten @entity1 with mosaic pattern revealed air trapping areas on end expiratory scans. Twelve @entity1 had abnormal PFT and all had restrictive type of involvement. Ten of these 12 @entity1 had abnormal @entity2101 and the remaining two @entity1 had normal @entity2101 . On the other hand, eight @entity1 with normal PFT had abnormalities on @entity2101 . CONCLUSION: @entity1 with early @entity1691 frequently have abnormalities on @entity2101 , even though they have normal PFT and chest X-ray. Small airway involvement was found as frequent as @entity401 in early @entity1691 .
