Figure 1(A-E)
Axial images at diagnosis show bilateral lung nodules with a perilymphatic pattern. Note the peribronchovascular (A and B; see arrowheads), interlobular (C; see arrowheads), and subpleural involvement (D; see arrowheads). The confluence of many small nodules forms consolidations with irregular margins (B; see asterisk). The lesions mainly involve the upper and middle zones (E, coronal view; see arrowheads)
Figure 2(A-D)
Figure 2(A-D)
The thoracoscopic biopsy shows an interstitial fibrotic lesion with a reticular and nodular pattern (A, H and E stain, magnification 40×) and a subpleural and septal distribution. The lesion is characterized by multiple non-confluent granulomas (B, 100×) accompanied by collagen deposition devoid of significant inflammation and necrosis (C, 200×). The granulomas is made of epitheliod hystiocytes with few multinuclear giant cells (D, 400×)

Two years later follow-up HRCT images. Bilaterally, some small linear opacities persist (A and B; see arrowheads), no further parenchymal abnormalities are appreciable
