Figure 1. Pulmonary involvement of HES, computed tomography at initial diagnosis: patchy images of HES involvement (arrows). There was no pathological lymphadenomegaly in the mediastinum. In the evaluation of the lung parenchyma structures, ground glass patchy consolidation areas were observed at the level of the middle and lower lobe segments. Ground glass densities were determined at the level of the upper lobe segments, compatible with proliferative phase COVID-19 pneumonia. HES: Hypereosinophilic syndrome; COVID-19: coronavirus disease 2019.
