Background/Purpose:Connective tissue diseases (CTD) can cause intrathoracic involvement, increasing patientsmorbidity and mortality. High-resolution computed tomography (HRCT) is a key method forevaluation of these manifestations. The aim of this study is to describe clinical features and toevaluate intrathoracic HRCT findings in patients with CTD.Methods:Retrospective descriptive study, from January 2010 to December 2016.We evaluated HRCT findingsin patients with CTD. We excluded patients under 18 years of age, pregnant, diagnosis ofvasculitis, respiratory infections, drug toxicity, and previous thoracic surgery or radiotherapy. Datawere analyzed using SPSS 17.0 software.Results:Out of 199 patients, 96 had rheumatoid arthritis (RA), 29 systemic lupus erythematosus (SLE), 26systemic sclerosis (SSc), 23 inflammatory myopathies (IM), 22 primary Sjögren?s syndrome (pSS)and 3 mixed connective tissue disease (MCTD). The baseline characteristics of patients are shownin table 1.There was a higher frequency of bronchiectasis in RA, esophageal dilation in SSc and pleuraleffusion in SLE (p
