Chest X-ray (IMAGE) Radiological Society of North America Caption Follow-up chest x-ray. The patient was diagnosed with silicosis based on clinical history, imaging features, and bronchoscopy with biopsy, which demonstrated silica crystals with fibrotic nodules. There is persistent small left-sided pneumothorax/lung collapse (red arrow), asymmetric right upper lung thickening (yellow arrow), and findings consistent with progressive massive fibrosis (orange circle), indicating complicated and advanced silicosis. The patient is still working in the countertop-cutting industry due to lack of other job opportunities.
