A-C, Representative lung ultrasound on day 3, day 10, and day 16. A, This lung ultrasound showed A-lines, which are normal lung artifacts, on the right upper anterior lung zone on day 3. Eleven out of 12 lung zones revealed A-lines. B, On day 10 at the peak of the inflammatory symptoms, 8 out of 12 lung zones demonstrated confluent B-lines as shown in this figure. This image was obtained on the right upper anterior lung zone. C, On day 16, which was 5 days after tocilizumab, only 3 out of 12 lung zones had B-lines. The B-lines on the right upper anterior lung zone were resolved (images are courtesy of Dr Liu)
