CTICasesAccelerated Silicosis
Imaging findings
Chest CT in a 50-year-old worker with 12 years of unprotected occupational exposure to artificial stone dust shows progressive upper lobe predominant perilymphatic nodularity, mass-like coalesced consolidation, and mild mediastinal nodal calcification.
Key takeaways
Accelerated silicosis is resurging among workers in artificial stone countertop manufacturing due to high silica content and inadequate ventilation. Radiologically, it behaves like classic silicosis but develops within 5-15 years, presenting with upper-zone predominant perilymphatic nodules and progressive massive fibrosis.
