These films come from an article published in the New York Times on April 27, 2020. The article reported on the successful treatment of a severely ill COVID-19 patient. I put these radiographs on the web site because the film in the middle illustrates a pneumonia so extensive that there is a silhouette sign for the entire heart. That is, one cannot see either the left or right border of the heart because everywhere it lies up against fluid-filled lung. If you want to review the concept of silhouetting, go to the lecture on Radiology of the Thorax.
