Imaging Diagnosis of Interstitial Pneumonia with Emphysema (Combined Pulmonary Fibrosis and Emphysema)

Figure 1

Diffuse interstitial pneumonia (nonspecific interstitial pneumonia (NSIP) pattern) with emphysema. (a) Chest X-ray shows bibasilar ground glass and reticular opacity. Volumes of bilateral lungs are almost normal. (b) High-resolution computed tomography (HRCT) of upper lung shows centrilobular pulmonary emphysema. (c), (d) HRCT of lower lung shows ground glass opacity along the bronchovascular bundle including cysts with varying size. Distribution of abnormal opacity mimics NSIP.
