Chest radiograph showing homogenous opacity in the left lower zone with shifting of the mediastinum to the left.
Figure 2:
CT pulmonary angiography. (A) In the lung window below the level of the arch of the aorta, the left lung is not visualised with a shift of mediastinum to the left with compensatory hyperinflation of the right lung. (B) Tracheal division is seen with abrupt cut-off of the left main bronchus. (C) In mediastinal window at the same level shows the pulmonary trunk with the absence of branching on the left side. (D) Left pulmonary vasculature is not seen with a normal right main pulmonary artery.
Figure 3:
Bronchoscopy: Carina is dividing into left main bronchus and right main bronchus, but the left main bronchus is ending in a blind loop, and no openings are seen.
