A chest CT showed findings of pulmonary thromboembolism, alveolar infiltrates
in the left lung and interstitial fibrotic lesions, bulla, bilateral pleural effusion and right cardiomegaly (Figure 1 C).
The consultant suspects a pulmonary-renal syndrome because of bilateral alveolar infiltrates
(diffuse alveolar hemorrhage).
The lesions of chronic hydrocarbon aspiration are quite different, presenting with pseudotumours' or crazy paving alveolar infiltrates
having negative CT attenuation values (Hounsfield Units <0)(25).
Her chest x-ray showed diffuse interstitial and alveolar infiltrates
in a bat wing pattern.
A chest x-ray showed new, multifocal, and extensive alveolar infiltrates
throughout the right hemithorax.
Two formats were used for this readings: I) conventional, in which the presence, localization and type of infiltrates were evaluated, discriminating between alveolar infiltrates
(with or without air bronchogram), and interstitial infiltrates (of nodular, reticular or mixed types); unilobar or multilobar infiltrates, and pleural effusion; and II) quantitative scale, which assigns a score according to the extension of the pulmonary injury, determined by the number of affected intercostal spaces.
Focal infiltrates, nodules and diffuse alveolar infiltrates
are less common findings and were noted in 2 of our patients.
The chest X-ray showed massive alveolar infiltrates
The CT scan confirmed diffuse patchy alveolar infiltrates
and small bilateral pleural effusions (Figure 2).
1) He had the Rapid onset of respiratory distress, diffuse crackles on lung examination, bilateral, confluent alveolar infiltrates
on chest roentgenogram and progressive arterial hypoxemia refractory to supplemental oxygen therapy.
A diagnosis of DAH should be entertained only when a patient presents with diffuse alveolar infiltrates
