Chest x-ray at clinical onset of symptoms, consistent with diffuse alveolar hemorrhage (DAH). There can be observed infiltrative opacification pattern mainly seen in the mid zones with apical sparing suggestive for impaired pulmonary microcirculation. There can be noticed areas of subdiaphragmatic air due to laparoscopy.

His initial chest x-ray (Figure 1) showed infiltrative opacification pattern mainly seen in the mid zones with apical sparing suggestive for impaired pulmonary microcirculation, raising the suspect of DAH.
Chest CT scan without contrast medium confirming the diagnosis of DAH.

To further investigate our hypothesis, a chest CT scan (Figure 2) was performed, which revealed multiple dense opacities with blurred, confluent margins due to diffuse alveolar involvement in the pulmonary lobes.
Chest x-ray after 48 h showing both lungs clear of significant parenchymal opacities and no signs of pleural effusions.

The patient's general conditions rapidly improved after 24 h: he was no longer dyspneic, and oxygen supplementation was stopped on day 2 of hospitalization after a second chest radiograph (Figure 3) revealed the resolution of DAH.
