Figure 17: Panel A CT scan (lung window) of a 43-year-old man with sarcoidosis demonstrates bilateral perihilar interstitial nodules. Note their central location and perivascular distribution (arrows). Panel B CT scan (lung window) of a 39-year-old woman with sarcoidosis demonstrates profuse bilateral parenchymal nodules. Confluent areas of high attenuation are noted in the lower lobes and lingula. Panel C High-power photomicrograph (original magnification, X120; H-E stain) of the lung parenchyma demonstrates multiple well-defined nodular perivascular granulomas (arrows).
