[Lung involvement in connective tissue diseases].

Connective tissue diseases as systemic autoimmune diseases are frequently associated with lung involvement. The diagnostics are often delayed by initially mild and unspecific symptoms. As lung involvement in these diseases can be chronically progressive and sometimes rapidly progressive, early and regular screening and monitoring are essential. This article focuses on typical findings and the diagnostic value of useful examination methods. Ideally, the diagnostics and treatment of lung involvement in connective tissue disease should be performed on an interdisciplinary basis in collaboration between pulmonology and rheumatology.
