Initial and follow-up CT images in a 71-year-old woman with COVID-19 pneumonia. Unenhanced initial CT performed before RT-PCR confirmation (A,C) shows bilateral peripheral ground-glass in the dorsal segment of upper (a) and lower lobes (C) (arrows). Contrast-enhanced CT (B,dD) performed 6 days later to rule out pulmonary embolism demonstrates linear consolidations typical for an organizing pneumonia pattern (arrowheads).
