- enlarged heart with blurred margins
- diffuse, bilateral, inhomogeneous airspace opacities, which do not show a perihilar predominance. Resultant aerobronchograms.
Considering the known chronic heart disease, and multiple other comorbidities, as well as the symptoms heart failure and resultant pulmonary edema could be on the list of differentials. However the absence of a perihilar predominance and the patchy distribution of airspace opacities also raises the possibility of diffuse pneumonia, including COVID-19 infection. This patient (although afebrile and without a cough) had a very high CRP and consequently tested positive for SARS-CoV-2 by RT-PCR.
