CT imaging findings; a A mass like lesion was shown in the left upper lobe apicoposterior segment. b Dimensional regression of the mass like lesion and a consolidated area containing air bronchograms was observed in the left upper lobe apicoposterior segment 6 days later. c Follow-up CT scan 6 days later showed typical COVID-19 findings with multifocal segmental ground glass opacity infiltration and consolidation with air-bronchogram along the bronchovascular bundles and in subpleural areas with associated interlobular septal thickening and minimal pleural effusion in the left lower lobe
