Plain chest x-rays reveal decreased lung volumes, typically with prominent reticular interstitial markings near the lung bases.

It often extends over the area of an entire lobe or lung, with fibrotic areas involving costophrenic angles, apices, lung bases, and interlobar fissures.

It initially affects the lung bases and usually manifests after 15 or more years from initial exposure.

The findings usually appear as small, irregular parenchymal opacities, primarily in the lung bases.

Littering both lung bases were opaque speckles that turned out to be barium, a metal that exposes internal organs on X-rays.

There are rhonchi in lung bases.

Chest radiography confirmed bilateral pleural effusions, more considerable on the left, and linear atelectasis at the lung bases.

It can be associated with dullness to percussion over the left subscapular area due to compression of the left lung base.

Subsequently, the patient underwent a computed tomography (CT)-guided biopsy of an area in the right lung base (Figure 1A, left panel).

Sometimes fine inspiratory crackles can be heard at the lung bases on auscultation.
