COVID-19 pneumonia

Case contributed by Antonio Rodrigues de Aguiar Neto


Headache, fever, nasal congestion, cough, dyspnea, pleuritic pain, myalgia, loss of smell, and taste, with the onset of symptoms 11 days ago.

Patient Data

Age: 45 years
Gender: Female

13 days from symptoms onset


CT shows bilateral, multi-lobar areas of mixed airspace consolidations with ground-glass opacities in both lungs, some of them with reticular and interlobular septal thickening featuring the crazy-paving pattern. The lesions are mostly in the peripheral parts of the lungs. Small bilateral pleural effusion

This patient tested positive for SARS-CoV-2, and the CT findings are consistent for peak stages (stages 3) COVID-19 pneumonia.

45 days from symptoms onset


CT reveals regression of the pleural effusion and of the lung abnormalities related to pneumonia COVID-19, leaving rare and tenuous bilateral residual ground-glass focal areas, usually found at the late/absorption stage (stage 4).


Case Discussion

Covid-19 is a disease caused by SARS-CoV-2 1-6. Chest CT can help guide the clinical decision and monitor disease progression 1-6. In stage 3 (peak stage, 9-13 days from onset of the symptoms), consolidations become prevalent concerning ground-glass opacities (GGOs) 1-6. In stage 4 (absorption/late stage, After 14 days), the consolidations are gradually absorbed and replaced by subpleural parenchymal bands and residual faint GGOs, which can persist as long as one month and beyond 1-6.

This case illustrates the temporal CT changes of peak stage (stages 3), improving at the late/absorption stage (stage 4) of COVID-19 pneumonia.
