Cat.SignificadoCondutaRiscoFonte
typical
Typical appearance
Typical appearance: CT features commonly and relatively specifically reported in COVID-19 pneumonia, i.e. bilateral, multifocal, peripheral and rounded ground-glass opacities, with or without consolidation, and/or features of organizing pneumonia (may include 'crazy-paving' / interlobular septal thickening superimposed on ground-glass).		——
okfonte
PMC7255403, Table 1 and accompanying text, 'Typical appearance' ('features ... frequently and more specifically seen in COVID-19 pneumonia'); peripheral/rounded/bilateral distribution corroborated by PMC7335944.
indeterminate
Indeterminate appearance
Indeterminate appearance: absence of the typical features together with findings reported in COVID-19 but not specific enough for a confident diagnosis, e.g. ground-glass opacities (with or without consolidation) in a nonrounded and nonperipheral distribution (perihilar, diffuse, or unilateral), or only a few small nonrounded/nonperipheral ground-glass opacities.		——
okfonte
PMC7255403, Table 1, 'Indeterminate appearance' ('not specific enough to arrive at a relatively confident radiological diagnosis'); nonrounded/nonperipheral distribution detail corroborated by PMC7335944.
atypical
Atypical appearance
Atypical appearance: absence of typical and indeterminate features, with findings uncommon or not reported in COVID-19 pneumonia, e.g. lobar or segmental consolidation without ground-glass opacities, discrete centrilobular nodules / tree-in-bud opacities, lung cavitation, or smooth interlobular septal thickening with pleural effusion.		——
okfonte
PMC7255403, Table 1, 'Atypical appearance' ('uncommon or not occurring in COVID-19 pneumonia ... lobar/segmental consolidation without GGO, cavitation, tree-in-bud / centrilobular nodules'); corroborated by PMC7335944.
negative
Negative for pneumonia
Negative for pneumonia: no CT features to suggest pneumonia; specifically, no parenchymal abnormality attributable to infection - ground-glass opacities and consolidation are absent.		——
okfonte
PMC7255403, Table 1, 'Negative for pneumonia' ('no parenchymal abnormalities ... GGO and consolidation are absent').
