Correct!
2. The chest CT shows multifocal peripheral ground-glass opacities and consolidation
The chest CT shows multifocal areas of ground-glass opacity and consolidation in the biapical, medial right upper lobe, and right lower lobe subpleural and ground-glass opacity and consolidation (arrows). A small focus of low attenuation (arrowhead) is present in the subpleural right lower lobe consolidation. Mild right peribronchial and mediastinal lymph node enlargement is present. No features of fibrosis- such as traction bronchiectasis, intralobular lines, architectural distortion, and honeycombing- are evident. No evidence of cavitary lung nodules is seen. While some ground-glass opacity is present, it is unassociated with interlobular septal thickening.
A repeat complete blood count was performed which again showed a white blood cell count within the normal range, but mild eosinophilia-0.75 x 109 / L (normal, 0.03 – 0.48 x 109 / L) was again noted.
