Patient Data

Age: 40 years
Gender: Female

Day 9 from symptoms onset


There are bilateral, multiple rounded consolidations with surrounding ground-glass opacities and the intra/interlobular septal thickening - crazy-paving pattern. The lesions are mostly in the peripheral and posterior parts of the lungs.

No pleural effusion, neither enlarged mediastinal lymph nodes.

This patient tested positive for coronavirus disease-19 and had the CT imaging features for the peak stage (stage 3) COVID-19 pneumonia.

Case Discussion

COVID-19 is a disease caused by SARS-CoV-2 1-5. Chest CT presents a temporal dynamic radiologic pattern of this respiratory infection, characterized by four stages 1-5. In the disease's peak stage (stage 3, day 9-13 from symptoms onset), consolidations are the predominant lesion 1-5, which may be associated with ground-glass opacities, crazy-paving patterns, and occasionally parenchymal bands 1-5.

This case shows a patient with laboratory-confirmed SARS-CoV-2 and the typical CT temporal changes of peak stage (stage 3) of COVID-19 pneumonia.
