Baseline chest CT shows ground-glass opacities (GGO) (arrowheads) in the bilateral lung parenchyma and multiple solid nodules that the largest one has a diameter of 13 mm (arrow), which is at the anterior segment of the left upper lobe. (A). In the lower lobes, many solid nodules with a maximum size of 8 mm on the right upper lobe (black arrow) and GGO in the nodular form (black arrowhead) are observed (B). The Maximum Intensity Projection (MIP) image shows bilateral randomly distributed multiple solid nodules.

Non-enhanced chest computed tomography (CT) revealed bilateral, diffuse, randomly distributed, sharply defined solid nodules, the largest of which reaches 13 mm in diameter, accompanied by peripheral patchy and nodular GGO (Figure 1).
In control chest CT (45 days after disease onset), nodules in the upper lobes and GGO have completely disappeared, and a sequelae band is observed in the place of the nodule in the left anterior segment in Figure 1A. (A). Nodules and GGO have regressed almost entirely in the bilateral lower lobes. (B). MIP axial CT shows the disappearance of most nodules (C).

In the chest CT (45 days after the baseline CT), it was observed that the GGO disappeared completely; while most of the nodules disappeared, some of them became significantly smaller, and the biopsy was canceled (Figure 2).
