Background
The COVID-19 pandemic, caused by SARS-CoV-2 infection, has resulted in multiple ICU admissions worldwide. Radiologists play a key role in monitoring progress and identifying complications related to the disease.

Educational Goals / Teaching Points
This exhibit aims to describe the pathophysiology of severe COVID-19 pneumonia; illustrate imaging appearance of ARDS-like changes associated with severe COVID-19 pneumonia; describe pulmonary vascular and cardiac manifestations; identify therapy-related complications (barotrauma, ventilator-associated lung injury); identify co-existent bacterial or fungal infection; and discuss fibrosis-like sequelae of severe COVID-19 pneumonia.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Key points of this exhibit include: pattern of worsening parenchymal opacities in severe COVID-19 pneumonia; vascular dilatation and vascular thrombosis; myocarditis, pericardial effusion, and left ventricular failure; pneumothorax, pneumomediastinum, and cystic lung injury; co-existent bacterial or fungal infection (focal opacities, lobar consolidation, centrilobular tree-in-bud opacities, and pleural effusions); and post-COVID-19 lung injury (parenchymal bands, architectural distortion, traction bronchiectasis).

Conclusion
It is important for radiologists to recognize sequelae of severe COVID-19 pneumonia, be aware of sequential changes in imaging findings, and identify potential complications.
