P/F, LDH, and CT findings were improved (Fig. 1). PSL 30mg (0.5mg/kg/day) was started after the pulse therapy, and the dose was gradually tapered. MP improved P/F, LDH, and CT findings in all cases in spite of bimodal worseness after intubation (Figs. 1 and 2).

Computed tomography of the chest during the clinical course in case 1. It showed bilateral peripheral ground glass opacities on day 11 (on admission). These opacities progressed consolidation with traction bronchiectasis and volume loss on day 19 (the day steroid pulse therapy was started). Patient almost recovered from these findings on day 61.
