Head computed tomography images of a 64-year-old man with asymptomatic symptom for coronavirus disease 2019. (a) Axial showing subarachnoid space dilated associated with cortical atrophy (Red arrows). (b) Choroid plexus calcification in the lateral ventricles (Red arrows).

The CT scan revealed general cerebral atrophy (corresponding to the patient's age) and discreet gliotic lesions but no changes to the brain parenchyma [Figure 1].
Chest computed tomography (CT) images of a 64-year- old man with asymptomatic symptom for coronavirus disease 2019 (COVID-19). (a-d) Axial chest CT scans showing multifocal and bilateral ground-glass opacities, with peripheral and posterior predominance (Red arrows), which are typical pulmonary findings of COVID-19 infection (confirmed by reverse transcriptase polymerase chain reaction).

Alveolar changes predominantly, such as ground-glass opacities, focal consolidations, and mixed opacities (including a reversed halo sign), with bilateral and multifocal involvement, peripheral distribution, predominantly in the middle, lower, and posterior lung fields, septal thickening, and reticular changes superimposed on alveolar changes [Figure 2]. Also incipient lung scarring (fibrotic bands) and pleural effusion with ground-glass opacities especially predominated shown in [Figure 3] and mediastinal lymphonodes [Figure 4].
Chest computed tomography (CT) images of a 64-year-old man with asymptomatic symptom for coronavirus disease 2019. Chest CT with different planes, coronal plane (a and b) reconstruction shows bilateral multifocal ground-glass opacities (Red arrows) and sagittal plane (c and d) images show multiple patchy and bilateral areas of ground-glass opacities with a posterior predominance (Red arrows).
