FIG. 2.

(A) Baseline high-resolution computed tomography (HRCT) image of the chest. Mild subpleural interlobular septal thickening with ground glass attenuation is seen in both lungs. (B) HRCT image just after the initial onset of pneumothorax. Subpleural fibrosis and bronchiectasis worsened with a definite right-sided pneumothorax. (C) Follow-up HRCT on the same level of the chest. The image was taken after cessation of etanercept and 3 months after medication with adalimumab. One year after etanercept cessation, interstitial fibrosis is still noted but is relatively stable in its degree and extent.
