Ground glass opacities and consolidation in both lower lobe basal segments
Peripheral subpleural area of an incomplete rim of consolidation in the posterior and laterobasal segments of the right lower lobe, surrounding a central region of ground glass opacities, consistent with the "reversed halo sign"
This patient had positive RT-PCR testing for COVID-19.
Reversed halo sign has been found to prefer a peripheral lower lobe distribution in COVID-19 pneumonia.
