Presentation
Fever, dyspnoea, cough, myalgia, and headache (Rt-PCR positive for Covid-19)
Patient Data
Axial chest CT scan without contrast shows multifocal bilateral patchy ground-glass opacities with multiple round and target-like lesions with a central high attenuation core and peripheral ring-like opacities on both lungs field which known as pulmonary target sign in a known case of Covid-19 pneumonia.
Case Discussion
The typical pattern of CT imaging features of COVID-19 pneumonia comprised predominantly of multifocal subpleural patchy ground-glass opacity (GGO), patchy consolidation, and crazy-paving 4.
Pulmonary target sign 1,3 and its variants such as rings of Saturn 2, reversed halo or atoll sign are uncommon but unique and specific imaging findings of Covid-19 pneumonia in chest CT. They present as a focal core ground glass or consolidative opacity surrounded with a ring-like opacity “pulmonary target sign” and two or more ring-like opacities immediately around “rings of Saturn”.
