Abstract

Ankylosing spondylits is a prototype of spondyloarthropathy tropates. During the progression of ankylosing spondylitis, which can destroy many systems, pleuroparanchymal involvement occurs rarely. The most commonly observed lesion is the fibrobullous disease on the upper lobes. Chronic aspergillus colonization has been reported in a quite significant percentage of the patients with ankylosing spondylits (50-65%). Pulmonary aspergilloma is the most observed clinical form in patients with ankylosing spondylitis. Invasive pulmonary aspergillosis occurs especially in patients with immunesupression. Here we shall present a case with ankylosing spondylitis complicated by chronic necrotizing pulmonary aspergillosis which is a form of invasive pulmonary aspergillosis.
