  • Figure 1
    Initial chest radiograph

    Reduced right lung volume is seen with decreased right lung markings and ipsilateral tracheal/mediastinal shift. The right pulmonary artery is not visualized. Apparent widening of the right paratracheal stripe is also...

    No definite mediastinal/lung parenchymal abnormality is noted in right paratracheal region. Mediastinal shift is seen to the right side with the SVC and azygos vein likely producing the right paratracheal opacity on...

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

    The right pulmonary artery is not visualized. Main pulmonary trunk and left pulmonary artery appear unremarkable. Right internal mammary artery(arrow) appears enlarged in size. Prominent vascular collaterals seen in...

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

    Vascular collaterals are seen along the anterior and anterolateral chest wall/pleura (arrows).

    The right lung volume appears reduced. Nodular thickening of the right lung fissures is seen. Nodularity is also seen along the anterolateral pleural surface in right hemithorax.

     
    Area of Interest: Lung; Vascular; Imaging Technique: CT-High Resolution; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Nodularity seen along tight pleural surface and fissure. Subpleural emphysematous changes in right mid/lower lobe.
