Chronic airspace disease: Review of the causes and key computed tomography findings

Figure 1 Alveolar sarcoidosis. A and B: Non-contrast computed tomography of the chest, lung window at baseline (A) and after 5 mo (B) in a 46-year-old man with cough and biopsy-proven sarcoidosis. Pleural-based consolidative opacity remained unchanged (arrows). Typical sarcoidosis findings of peribronchovascular and perilymphatic nodularity can be well-seen in the follow-up image (arrowhead in B); C: The liver was also involved with subtle hypodense lesions in the right and left hepatic lobes (arrows).
