  • Figure 1
    CT
     

    CT axial view showed the cardiac dextroposition and smaller right lung (hypogenetic lung).

     
    Area of Interest: Lung; Paediatric; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Lung tissue in the lower part of the right posterior hemithorax connected across the midline to the left lower lobe with a pleural fissure divided (arrow).

     
    Area of Interest: Lung; Paediatric; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Abscess; Congenital;
     
     
  • Figure 2
    CT-Angiography
     

    Volume rendering reconstuction (VRT) clearly showed that the right plumonary artery and veins were smaller than the left one, which confirmed the diagnosis of hypogenetic lung.

     
    Area of Interest: Anatomy; Cardiac; Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Contrast agent-intravenous; Special Focus: Congenital;

    Posterior view of VRT showed all of the right plumonary veins, including those of pseudohorseshoe lung, drained into the mouth of inferior vena cava.

     
    Area of Interest: Anatomy; Cardiovascular system; Computer applications; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Computer Applications-Detection, diagnosis; Contrast agent-intravenous; Special Focus: Congenital;

    Anterior view of VRT showed dextroposition of the heart. Other combined abnormalities could be found on CTA images, such as dilated azygos veins (black arrow).

     
    Area of Interest: Cardiac; Cardiovascular system; Computer applications; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Computer Applications-Detection, diagnosis; Contrast agent-intravenous; Special Focus: Congenital;

    Multi-planar reconstruction showed all of the right plumonary veins drained into the mouth of inferior vena cava.

     
    Area of Interest: Anatomy; Cardiovascular system; Computer applications; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Computer Applications-Detection, diagnosis; Contrast agent-intravenous; Special Focus: Congenital;

    Multi-planar reconstruction showed all of the right plumonary veins, including those of pseudohorseshoe lung(white triangle), drained into the mouth of inferior vena cava.

     
    Area of Interest: Anatomy; Cardiovascular system; Computer applications; Imaging Technique: CT-Angiography; Procedure: Computer Applications-3D; Computer Applications-Detection, diagnosis; Contrast agent-intravenous; Special Focus: Congenital;

    Other combined abnormalities could be found on CTA images, such as dilated azygos veins (black arrow) and atrium septal defect (white arrow).

  • Figure 3
    CT
     

    VRT showed hypogenesis of the right lung and trachea trifurcation, even the pseudohorseshoe lung (arrow).

     
    Area of Interest: Anatomy; Computer applications; Lung; Imaging Technique: CT; Procedure: Computer Applications-3D; Computer Applications-Detection, diagnosis; Normal variants; Special Focus: Congenital;

    Minimum intensity projection showed hypogenesis of the right lung and trachea trifurcation, even the pseudohorseshoe lung(arrow).

     
    Area of Interest: Anatomy; Computer applications; Lung; Imaging Technique: CT; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Congenital;

    Bifurcation at the root of right principal bronchus meant trachea trifurcation by virtual endoscopy.
