Combined pulmonary fibrosis emphysema syndrome complicated by pneumomediastinum and subcutaneous emphysema


In smokers, the combination of emphysema and fibrosis is becoming more and more recognized. Patients are almost exclusively men in their 6th and 7th decades. Lung volumes are relatively preserved. Honeycombing, reticular opacities, paraseptal and centrilobular emphysema, and traction bronchiectasis are the most frequent findings at high-resolution CT.
