Progressive Massive Fibrosis on Chest X-Ray In a construction worker presenting with shortness of breath. Progressive Massive Fibrosis is a chronic interstitial lung disease with a complex etiology that can occur after cumulative dust exposure. It is a severe form of pneumoconiosis which is caused by disease progression, coalescence of the nodules and progressive cicatricial retraction resulting in benign, upper lobe masses. It is seen in silicosis, coal worker’s pneumoconiosis and sometimes in talcosis. Dr. Devpriyo Pal @drdevrad #Progressive #Massive #Fibrosis #Chest #XRay #CXR #silicosis #clinical #radiology
