3. Figure 2
A-C, Chest CT scans without contrast revealed multiple nodular lesions in all lobes of both lungs, variably distributed from the central zone to the periphery (black arrows). The nodules varied in size from 1.1 to 2.0 cm, having sharp to mildly irregular margins. The majority of these nodules are subpleural and fissural in location, anatomically a perilymphatic distribution. D-F, Soft tissue window at the same level demonstrates mildly heterogeneous soft tissue density (white arrows). No lymphadenopathy. No pleural or pericardial effusions. G, Some lesions had an associated “feeding vessel sign,” correlating with a perivascular distribution seen on pathology (white arrow).

4. Figure 3
A, Histologic sections of the right upper lobe lesion revealed a well-circumscribed, densely fibrotic nodule with a lymphoid rim at the interface (hematoxylin and eosin, original magnification × 4). B, At high magnification, the nodule was composed of thick collagen bundles, some of which were layered around vessels (hematoxylin and eosin, original magnification × 40).
