Multiple patchy opacities are seen at both lungs predominantly in peripheral regions highly suggestive for COVID19 pneumonia. Some of them show reverse halo sign which is defined as central ground-glass opacity surrounded by denser consolidation of crescentic shape or complete ring of at least 2 mm in thickness
Case Discussion
The reverse halo sign is classically seen in organizing pneumonia (OP), which is most commonly cryptogenic (COP) but can also be secondary to other causes particularly COVID 19.
This patient had positive RT-PCR testing for COVID-19.
