Sumario:The “bullseye” sign has been exclusively reported in patients suffering from coronavirus disease 2019 (COVID-19) pneumonia. It is theorized that this newly recognized computed tomography (CT) feature represents a sign of organizing pneumonia. Well established signs of organizing pneumonia also reported in COVID-19 patients include linear opacities, the “reversed halo” sign (or “atoll” sign), and a perilobular distribution of abnormalities. These findings are usually present on imaging in the intermediate and late stage of the disease. This is a case of simultaneous presence of the “bullseye” and the “reversed halo” sign on chest CT images of a COVID-19 patient examined 22 days after symptom onset.
