4. Unenhanced chest CT shows new areas of multifocal areas of ground-glass opacity
Unenhanced chest CT, performed 3 months following initial presentation and at the patient’s first outpatient follow up visit, shows patchy, multifocal ground-glass opacity associated with some mild reticulation. No pleural abnormality is present, nor are there features to suggest pulmonary fibrosis. The pulmonary opacities represent ground-glass opacity- increased lung attenuation that does not obscure the margins of pulmonary vessels and bronchial walls. Consolidation- increased lung attenuation that does obscure the margins of pulmonary vessels and bronchial walls- is lacking.
