Within 24 hr, patient died, and serologic tests subsequently confirmed that he had Hantavirus pulmonary syndrome. Follow-up chest radiograph obtained (with portable equipment) 24 hr after patient's marked clinical deterioration shows progression to extensive perihilar and upper lung zone consolidation with associated air bronchograms.

Within 24 hr, patient died, and serologic tests subsequently confirmed that he had Hantavirus pulmonary syndrome. Initial posteroanterior radiograph shows basilar and perihilar interstitial pattern.

Serologic tests subsequently confirmed Hantavirus pulmonary syndrome. Initial radiograph (obtained with portable equipment) shows normally sized heart and diffuse alveolar air-space pattern that is more predominant centrally and in mid and lower lung zones.

Serologic tests confirmed Hantavirus pulmonary syndrome. Posteroanterior chest radiograph obtained at presentation shows interstitial edema, Kerley B lines, pulmonary vascular congestion, and mild consolidation of perihilium and lower lung area.
