  • Figure 1
    Axial CT images
     

    Image at the level of the proximal third of the bronchus intermedius shows an anomalous bronchus (arrow) arising from the medial wall.

     
    Area of Interest: Thorax; Imaging Technique: CT;

    Slightly below 1a. Sequential CT images show the accessory bronchus progressing caudally towards the mediastinum.

     
    Area of Interest: Thorax; Imaging Technique: CT;

    Slightly below 1b. Post-therapeutic findings are also seen in the RUL and superior segment of the RLL, with multiple subsegmental atelectases, traction bronchiectases and pleural thickening.

     
    Area of Interest: Thorax; Imaging Technique: CT;

    Slightly below 1c.

     
    Area of Interest: Thorax; Imaging Technique: CT;

    Slightly below 1d.

     
    Area of Interest: Thorax; Imaging Technique: CT;

    Slightly below 1e. The accessory bronchus ends as a blind diverticulum (arrow) and is no longer seen.

     
    Area of Interest: Thorax; Imaging Technique: CT;
     
     
  • Figure 2
    Coronal CT image

    Coronal CT image shows to better advantage the position of the accessory cardiac bronchus (arrow) in the bronchial tree and its relation with the medial wall of the proximal third of the bronchus intermedius.

     
    Area of Interest: Thorax; Imaging Technique: CT;
     
     
  • Figure 3
    Virtual endobronchial view

    Virtual endobronchial view shows the accessory cardiac bronchus (left) separated by a spur (arrow) from the middle part of the bronchus intermedius; the origin of the RUL bronchus (right) is also seen.

     
    Area of Interest: Thorax; Imaging Technique: CT;
     
     
  • Figure 4
    Three-dimensional reconstruction

    Three-dimensional volume rendering image in the coronal plane clearly depicts the origin of the accessory cardiac bronchus from the medial wall of the bronchus intermedius, almost directly opposite to the origin of...
