Fig. 1From: Systemic sclerosis: correlation between lung abnormalities on high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs)A 43-year-old female patient presenting with progressive dyspnea. a–c Axial, coronal, and sagittal reformatted images of HRCT chest (lung window) showing interstitial lung disease in the form of bilateral fairly symmetrical predominantly subpleural ground glass opacification, thickening of interlobular and intralobular septae with traction bronchiectasis and bronchiolectasis and bilateral lower lobar reduced volume. Patulous esophagus is also noted on axial and coronal HRCT scans. d Axial mediastinal window showing prominent main pulmonary artery (about 3 cm) and enlarged prevascular lymph nodesBack to article page
