From: Imaging diagnosis of classical and new pneumoconiosis: predominant reticular HRCT pattern
59-year-old man with hard metal pneumoconiosis. Initial HRCT scan (a) shows scattered areas of ground-glass attenuation associated with fine reticulation and mild traction bronchiectasis. HRCT obtained 3Â years later (b) reveals increase in parenchymal abnormalities in extent, prominent reticulation, and progression of traction bronchiectasis. HRCT obtained 5Â years later (c) shows dense increased parenchymal opacities with traction bronchiectasis
