confirmed a right tracheal bronchus (Fig.
Infants with diffuse increased density, need for mechanical ventilation and respiratory acidosis according to blood gases were considered to have severe RDS, infants with pathcy areas of increased density on lung graphy and need for continuous positive airway pressure (CPCP) were considered to have moderate RDS and infants with scattered areas of increased density and/ or air bronchogram
for whom mask oxygen support was sufficient and who had no respiratory acidosis according to blood gases were considered to have mild RDS.
In some patients air bronchogram
formation (28%), feeding vessel sign (67%), pleural effusion and empyema can be observed (3), (4).
An SPN containing an air bronchogram
, bronchiologram, or cystic lucencies is highly suggestive of bronchogenic carcinoma, specifically adenocarcinoma (Figure 13).
Computed tomography (CT) of the chest revealed moderate right pleural effusion, small right pneumothorax, consolidation/atelectasis in the right lower lobe with air bronchograms
, and thickening of the distal esophagus and gastroesophageal junction.
The reported sensitivity of new or worsening opacity is reported to be 50-78% and air bronchograms
, 58-83%, however interobserver reliability is low.
Chest radiograph and computed tomography scan were performed, and results revealed extensive infiltrative shadows with air bronchograms
in the right lung; results were normal for the left lung.
performed about 2 years later on the second heterotopic heart transplant recipient demonstrated minimal compression of the right lung.
A chest computed tomography scan revealed a cavity at the right upper lobe and extended consolidation with air bronchograms
on both lower lobes (Figure 2).
On hospital day 7, chest computed tomography (CT) with contrast demonstrated right lower lobe consolidation with air bronchograms
and a complex right pleural effusion; there was no evidence for pulmonary embolism.
All patients' chest x-rays showed marked abnormalities, including extensive bilateral infiltration, lobar collapse, focal consolidation, and air bronchograms
A CT scan revealed consolidation with extensive air bronchograms
primarily in the anterior segment of the right upper lobe (Fig.
