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.
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.
The patient was referred to our clinic with a prediagnosis of malignancy-metastasis when bilateral diffuse nodular lesions were found on chest x-ray (Picture 1) and multiple nodular lesions with various localizations and sizes were found diffusely in both lungs on high-resolution lung tomography with the largest one in the superior segment of the lower lobe in the right lung with a size of 14x11 mm and additionally consolidation areas including air bronchograms
were found in the anterobasal segments of the lower lobe in the right lung and posterobasal segments of the lower lobe in the left lung.
Airspace disease was reported when confluent densities containing air bronchograms
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).
Bacterial pneumonia typically presents as lobar or segmental consolidation with air bronchograms
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
