In contrast, dense consolidation with air bronchogram is more frequent in community-acquired pneumonia due to pathogens other than M.
A dynamic sign of alveolar consolidation in bedside ultrasonography: Air Bronchogram. Interv Med Appl Sci 2014; 6: 402.
As shown in Table 2, the vast majority of the pulmonary infiltrates were considered as alveolar type, two-thirds had air bronchogram, one in three patients had pleural effusion, usually on one side, and one in four multilobar disease.
This case has not clinically revealed cardiac dysfunction, but diastolic dysfunction might have potentially progressed because of elevation of NT-pro BNP, slight dilatation of the left ventricle, and alveolar syndrome with air bronchogram on the CT chest.
(b) EBUS showed heterogeneous echogenicity, along with linear- discrete air bronchogram. (c) Histologic specimen of the biopsy revealed interstitial homogenous fibrosis and chronic inflammation (hematoxylin and eosin staining, 200x).
At the time of admission, the chest CT showed diffuse exudation, uniform ground-glass shadow, which is more obvious in the right lung, visible air bronchogram sign in the right lower lobe of the lung.
[7] Typical chest X-ray findings of low volume lungs with a diffuse reticulogranular pattern and air bronchogram supported the diagnosis.
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 severity of RDS is further divided into Mild (1-3), Moderate (4-6) and Severe (7-10) by using Downe's score.
An SPN containing an air bronchogram, bronchiologram, or cystic lucencies is highly suggestive of bronchogenic carcinoma, specifically adenocarcinoma (Figure 13).
The main features of atelectasis on LUS include lung consolidation and air bronchograms.[sup][5],[44],[45] In most cases, a static air bronchogram is seen, whereas a dynamic air bronchogram is not.
(3) An air bronchogram is usually associated with lobar pneumonia and suggests air in bronchi against a background of consolidation.
