The clinical findings are variable ranges from flu like symptoms to severe respiratory distress syndrome.Multidetector computed tomography is the most sensitive imaging technique for the diagnosis of COVID-19, showing different lung alterations such as GGO, consolidations, crazy paving, vascular dilatation, parenchymal bands and architectural distortion; regarding disease course several radiological patterns are observed.
