In contrast, dense consolidation with air bronchogram
is more frequent in community-acquired pneumonia due to pathogens other than M.
The "aerial dynamic bronchogram
", an ultrasound sign of alveolar consolidation.
Widened mediastinum and retrocardiac opacity showing no air bronchogram
Chest radiographs showed a severe bilateral air bronchogram
in the lung field.
Radiographic features were recorded as either normal, presence of patchy opacities in one or more lobes, or lobar/segmental consolidation with or without an air bronchogram
. The radiograph findings were corroborated by a consultant radiologist.
When alveolar injury is moderate to severe, it is seen as poorly defined areas of consolidation, with no air bronchogram
sign, as a result of bronchial obstruction caused by secretions and/or blood.
confirmed a right tracheal bronchus (Fig.
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.
Patients having signs/ symptoms of cardiac failure like raised jugular venous pressure, raised central venous pressure and radiological features of high pressure oedema (cardiomegaly, dilated upper lobe vessels, Kerley's lines, central lung shadowing with absence of air bronchogram
), ECG suggestive of ischaemic heart disease or accelerated hypertension or hypertensive heart disease as documented by 2D echo.
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.
