Chest CT and X-ray images. The upper panel (a and b) shows chest CT and the mid and lower panels (c–h) show chest X-ray. The images of chest CT on day 15 (a) and 22 (b) show patchy bilateral lung pulmonary infiltrates with predominant ground-glass components suspicious for pneumonia including COVID19. The new onset disease is mostly peripherally located (d–h) compared to previous asthma exaggeration 13 months ago (c) (mid and lower panel, chest X-ray). The disease was initially stabilized with corticosteroid, antibiotics (including azithromycin) and bronchodilator treatment and patient was not intubated until day 15 (d and e). The disease deteriorated on day 18 (f) and the hypoxemia required ventilation and diagnostic procedure of bronchoalveolar lavage and lung wedge biopsy (g). After the confirmation of COVID19, remdesivir, COVID19 convalescent plasma and continuous corticosteroid as well as bronchodilator led to slightly dissolved lung opacity (h)
