High-resolution computed tomography (HRCT) of the chest during the clinical course. A) Chest HRCT on admission showed non-segmental ground-glass opacities (GGOs) and consolidations, predominantly in the peripheral regions of both lungs. B) Immediately after four sessions of plasma exchange (PE), improvements in bilateral GGOs and consolidations could be seen. C) Eleven days after completing five sessions of PE, residual GGOs and reticular opacities were seen in both lungs. D) Six weeks after switching from tacrolimus to tofacitinib, chest HRCT showed improvements in residual GGOs and reticular opacities in both lungs.
