case_images: (A) Axial and (B) sagittal computed tomography images of the chest showing consolidation
  and subsegmental atelectasis in the right and left upper lobe, and consolidation and atelectasis,
  with tubular bronchiectasis, in the apical regions of the lower lobe.

case_images: An uncontrasted computed tomography (CT) scan was performed, which revealed bronchopneumonic changes with collapse and consolidation (Fig. 1). 
case_images: Axial computed tomography angiogram demonstrating an
  incomplete aortic sling noted as encasing both the trachea and
  oesophagus, with an impression of a fibrotic band or incomplete arterial
  communication in the quadrant between three o'clock and six o'clock.

case_images: This revealed a double aortic arch (DAA) vascular ring, with separate origins on the left and right common carotid and subclavian arteries as seen from the respective arms of the aortic sling (Fig. 2).

case_images: Review of his chest X-rays revealed significant narrowing of the airways and a structural anomaly was suspected (Fig. 3). 
case_images: Axial computed tomography chest image showing a complete aortic sling, which appears to encase the trachea and oesophagus.
