A dynamic sign of alveolar consolidation in bedside ultrasonography: Air Bronchogram
For the second reader, on the other hand, the variables absence of air bronchogram
, presence of pleural effusion, and infiltrates in the upper and lower right lobes, had the best Kappa scores (Table 4).
An SPN containing an air bronchogram
, bronchiologram, or cystic lucencies is highly suggestive of bronchogenic carcinoma, specifically adenocarcinoma (Figure 13).
7] Typical chest X-ray findings of low volume lungs with a diffuse reticulogranular pattern and air bronchogram
supported the diagnosis.
High resolution CT scan of the chest (Figure) revealed small effusion in the left chest with collapse and air bronchogram
, and pools of abscesses.
Respiratory distress was diagnosed on the basis of clinical criteria such as retraction of chest wall, cyanosis, hypoxemia, hypercarbia in ABG and radiological feature such as reticulogranular pattern and air bronchogram
The main features of RDS on LUS are as follows:[sup],, Lung consolidation with air bronchogram
, decrease or disappearance of lung sliding, disappearance of spared areas, alveolar-interstitial syndrome, pleural line abnormalities, pleural effusion, lung pulse and bilateral "white lung.
With severe atelectasis, air in the lung is greatly reduced, leading to the loss of the air bronchogram
signs and more widespread opacity of the lung fields.
The neonates were labelled as RDS if they developed respiratory distress within six hours and chest X-ray showed one or more of the following; poor expansion with air bronchogram
, reticulogranular pattern and ground glass opacity.
3) An air bronchogram
is usually associated with lobar pneumonia and suggests air in bronchi against a background of consolidation.
Computerized tomography of the thorax revealed mediastinal lymphadenopathy with a diameter of 15 mm, consolidation located at the right middle lobe containing air bronchogram
and with adjacent asiner nodules and ground glass opacification.
If two or more of these abnormalities are present, a chest radiograph should be evaluated for alveolar infiltrates or an air bronchogram
