-To recognize typical and atypical pulmonary image findings of scleroderma and pneumoconiosis. - To be aware of the possibility of having scleroderma and synchronic pneumoconiosis in the same patient and avoid “satisfaction of search” error.

Progressive systemic sclerosis or scleroderma is a generalized disease of the connective tissue in which up to 75% of the cases evidence pulmonary affection. This disease is commonly associated with usual interstitial pneumonia, non-specific interstitial pneumonia, pulmonary vasculitis, and pulmonary hypertension; nevertheless it can also be found associated with other lung diseases without a direct physiopathological relation. This is the case of pulmonary manifestations of scleroderma and synchronic inhalation lung disease. Pneumoconiosisis a broad group of lung diseases that result from the inhalation of dust...

1- HRCT findings of progressive systemic sclerosis HRCT findings of interstitial fibrosis in progressive systemic sclerosis are similar to those of idiopathic pulmonary fibrosis (IPF), including ground-glass opacity, consolidation, fine reticular opacities, coarse or irregular reticulation, traction bronchiectasis and honeycombing. Abnormalities typically show a subpleural and lower lobe predominance and often involve the lung periphery in a concentric fashion (Fig. 1). As with the other collagen diseases, there is a tendency for scleroderma to show a finger reticular pattern that is typical of IPF, and...

Seventyfive percent of patients with scleroderma have lung involvement in their chest HRCT, even without respiratory symptoms; most cases show some degree of interstitial fibrosis. . Other chest HRCT features may suggest synchronic illness and change management and prognostic.
