Usual Interstitial Pneumonia as an Initial Manifestation of Ankylosing Spondylitis

Abstract

Usual interstitial pneumonia as an initial manifestation of ankylosing spondylitis was not reported in the literature until now. We present a 57-year-old male who was admitted to our clinic due to left-sided nonpleuritic chest pain. High-resolution computed tomography scans showed bibasilar ground-glass pattern with honeycombing and apicobullous changes. Histopathologic examination of open lung biopsy, which was taken from left lower lobe was reported as usual interstitial pneumonia. Three years later, the patient described leg and back pain which met the modified New York criteria for ankylosing spondylitis. © 2007 Elsevier Ltd. All rights reserved.
