(A) Anterior-Posterior chest radiograph on hospital day 1 showing diffuse consolidative airspace disease. Radiograph was taken immediately following ECMO cannulation after transfer to our tertiary care facility. (B) Anterior-Posterior chest radiograph on hospital day 12 (4 days prior to discharge) showing decreased opacification of both the middle and lower lung zones with marked improvement of degree of airspace disease.

Chest radiography revealed bilateral pulmonary infiltrates (Figure 1A) and chest CT revealed widespread mixed groundglass and solid airspace opacities predominantly in the middle lung zones without evidence of pulmonary emboli (Figure 2). He underwent tracheostomy on day 4 of hospitalization, was weaned off of vasopressors and mechanical ventilation on days 3 and 8 (respectively), transferred out of the intensive care unit on day 12 (Figure 1B), and eventually discharged home on day 16.
Axial Chest CT angiography from hospital day 0 showing bilateral, extensive mixed groundglass and solid airspace opacities predominantly in the middle lung zones without evidence of pulmonary emboli.

Complete blood count then revealed ongoing leukocytosis (18.6 x 10 9/L) with evidence of peripheral eosinophilia (12.8%, 238 cells/mL) (see Figure 3 for complete blood cell count trends). Prednisone, 60 mg by mouth daily on day 7 of hospitalization. Peripheral eosinophil counts continued to downtrend while on corticosteroids (Figure 3D).
