Imaging Diagnosis of Interstitial Pneumonia with Emphysema (Combined Pulmonary Fibrosis and Emphysema)
Figure 7
Emphysema with fibrosis, acute exacerbation by anticancer drug. (a)–(e) Imaging findings before acute exacerbation. (a) Chest X-ray shows normal volume of bilateral lungs. There is reticular opacity in bilateral lower lung fields. (b), (c) High-resolution CT (HRCT). In upper lung, centrilobular emphysema, subpleural cyst, and profuse centrilobular small nodular opacities are identified. In lower lung, subpleural cysts and reticular opacity are noted abutting chest wall, most compatible with UIP pattern. (d)–(f) Imaging findings at acute exacerbation. (d) Chest X-ray shows diffuse ground glass opacity in the left entire lung. Pneumothorax is noted on right side. (e), (f) HRCT shows diffuse ground glass opacity overlapping preexisting interstitial shadow.
