The previously described extensive patchy bilateral ground-glass opacities are less dense and less conspicuous, but persist. Mild centrilobular emphysema is again noted, predominantly in the upper lobes. Mild air trapping is again identified at the lung bases, in keeping with small airways disease.
The 1.1 cm spiculated nodule in the posterior basal segment of the right lower lobe is unchanged. No new lung nodules or focal areas of lung parenchymal consolidation. A surgical staple line is seen at the posterior aspect of the right major fissure and lateral aspect of the superior segment of the right lower lobe, related to the previous open lung biopsy.
