Pt, patient; TSS, total severity score [13]; HRCT, high-resolution computed tomography.

^*Reported symptoms refer to the time of onset of the disease and/or the time of admission to the hospital.

^†Enlargement of pulmonary veins (inside and/or outside the areas of ground glass alveolar consolidation) was observed in all cases.
