Fig. 5From: Thymus CT-grading and rebound hyperplasia during COVID-19 infection: a CT volumetric study with multivariate linear regression analysisA 53-year-old male COVID-19 patient complained of fever, cough, loss of taste and smell: A Axial mediastinal window CT showed mixed soft tissue and fatty replacement of the thymic gland. The solid component is > 50% (grade 1) [red square]. B Axial lung window CT showed two right basal sub-pleural small ground-glass nodular opacities (orange arrows). C–D Axial 3D volumetry cuts highlighted the right basal small sub-pleural ground-glass opacities. The pathological lung volume was around 0.5% of the total lung volumeBack to article page
