  • Figure 1
    Axial CT scans of proximal interruption of RPA

    CTA-axial contiguous images (mediastinal window) reveal enlarged LPA and absence of mediastinal portion of RPA. Interlobar portions (arrow) of RPA are depicted significantly small. Arrowheads show hypertrophied...

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 2
    CTA-MIP coronal image of proximal interruption of RPA

    CTA-reconstructed MIP coronal image shows prominent LPA and its branches, whereas RPA is indistinct.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 3
    Axial CT image (lung window) of interruption of proximal RPA

    Axial CT image (lung window) shows normal lung parenchyma and herniation of the left lung into the right hemithorax (arrow).

CTA-axial contiguous images (mediastinal window) reveal enlarged LPA and absence of mediastinal portion of RPA. Interlobar portions (arrow) of RPA are depicted significantly small. Arrowheads show hypertrophied collateral vessels (probably representing bronchial arteries).
