Figure 6.

Dependent abnormality in a 72-year-old man with rheumatoid arthritis. (A) Axial CT image obtained with the patient supine shows ground-glass abnormality (arrowheads) in the subpleural lung area. (B) On the axial CT image obtained with the patient prone, the ground-glass abnormality has disappeared in the subpleural area but is seen in the middle lobe of the right lung (arrowhead). These findings are considered to indicate transient lung atelectasis.
