In the thorax CT examination of the patient, however, free fluid accumulation was determined in consolidation area involving air bronchogram in lower lobe of right lung and amid pleural leaves in the right hemithorax and atelectatic area in the right medium lobe (Figure 2).
The patients with radiological lesion (Chest x-ray) suggestive of collapse with direct signs like displacement of interlobar fissures, crowding of vessels and bronchi and indirect signs like local increase in opacity, elevation of hemidiaphragm, displacement of mediastinum, compensatory overinflation, displacement of the hila, approximation of ribs, absence of air bronchogram (In cases of resorption collapse only), absence of visibility of interlobar artery (In cases of lower lobe atelectasis only) are included in the study.
Patients were considered to present RDS if they presented PaO2 < 50-mmHg or central cyanosis in room air or needed supplemental oxygen to maintain their PaO2 > 50 mmHg and a chest X-ray showing small lung volume and a reticular granular appearance with air bronchogram.
A bronchogram refers to the phenomenon of visible bronchi.
In HAPE patients, the findings on LUS were unique and stable; in other words, apart from the intensive B-lines, no other findings were noted, including lung consolidation, air bronchogram, abnormal pleural line sliding, pleural effusion, or pleural thickening.
A chest CT scan revealed extension of the consolidation areas with air bronchogram in the left upper lobe and opacities in the right lung (Figure 3).
In real time, air can be seen moving through the bronchi, and this finding is known as a dynamic air bronchogram. The sensitivity of B-mode ultrasound imaging is approximately 90%.
During the initial assessment, laboratories tests were requested and the results showed eight times, from its normal value, elevated transaminases, hyperbilirubinemia at the expense of direct, hyperlactatemia and impaired renal function; his chest radiography has an increased heart silhouette; also, retrocardial opacity was observed without the air bronchogram (Figure 1).

An air bronchogram over the retrocardiac region was noted on chest radiography and pneumonia was suspected.
Chest X-rays of BALTOMA patients are usually nondiagnostic: solitary nodules (23%), multiple nodules (32%), air-space consolidation with air bronchogram (18%), patchy air-space and/or interstitial infiltrate (23%), peribronchial thickening (9%), hilar or mediastinal lymphadenopathy (5%), and pleural effusion (9%) were reported [4, 7].
The radiological evidence is the pulmonary edema with interstitial opacity, consolidations, air bronchogram, and Kerley's "B" lines.[8] The prognosis may vary from spontaneous resolution to life-threatening respiratory failure.
