title: [HRCT of the lung in collagenoses].
abstract: Collagen vascular diseases, representing systemic soft tissue disorders, may cause a broad spectrum of pathologic changes of the respiratory tract. The type and extent of manifestations can vary considerably among individuals and entities. This survey describes the chest radiographic and, in particular, high-resolution computed tomographic (HRCT) findings of individual lesions of the respiratory tract. It includes fibrosing alveolitis (alveolitis, interstitial pneumonia, pulmonary fibrosis) and bronchial (bronchitis/bronchiolitis, bronchiectasis), pleural and vascular manifestations, as well as lymphadenopathy and abnormalities related to therapy. We present typical patterns of changes in progressive systemic sclerosis (PSS, scleroderma), systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD, Sharp syndrome), Sjögren syndrome, overlap syndrome and rheumatoid arthritis (RA). Furthermore, we describe findings which are specific for individual entities such as esophageal involvement in PSS, acute pneumonitis and pulmonary hemorrhage in SLE, lymphoproliferative disease in Sjögren syndrome and necrobiotic nodules in RA.
