2. Figure 1
Chest radiograph of BCNU-treated patient, showing small right apical pneumothorax, bilateral apical pleural thickening, bilateral upper lobe fibrosis, and upward retraction of both hila. The pneumothorax was not evident on a radiograph obtained 1 year earlier.

3. Figure 2
Computed tomographic scans of the thorax in BCNU-treated patient, showing a small right apical pneumothorax, bilateral apical pleural thickening, and bilateral upper lobe subpleural fibrosis (top), multiple small right apical subpleural bullae (middle), and a small right pleural effusion (bottom).

4. Figure 3
Photomicrographs of lung biopsy specimen from BCNU-treated patient. Upper left, Pleural and interlobular septal fibrosis with portions of the intervening parenchyma relatively spared. Delicate interstitial fibrosis is present to a variable degree throughout the sections. Some tractional dilatation of membranous bronchioles is evident. Upper right, High-magnification view showing laminated appearance of denser peripheral fibrosis interfacing with looser fibrosis beneath. P = pleural surface. Lower left, High-magnification view showing parenchymal fibrosis with associated mild chronic inflammation. Lower right, Cystic membranous bronchiole adjacent to area of fibrosis (hematoxylin-eosin, original magnification: upper left, x20; upper right, x40; lower left, x60; lower right, x40).

5. Figure 4
Computed tomographic scans of the thorax in BCNU-treated patient 1 year after presentation, showing resolution of the right apical pneumothorax (left) and progression of the bilateral apical pleural thickening, bilateral subpleural fibrosis, and bilateral upper lobe fibrosis (left and right).
