  • Figure 1
    Chest CT
     

    An endobronchial lesion is seen within the lingula lobe bronchus. An area of different attenuation ratio is seen peripherally of the endobronchial lesion.

     
    Area of Interest: Thorax; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;

    An endobronchial lesion is seen within the lingula lobe bronchus (yellow arrow). An area of different attenuation ratio is seen peripherally of the endobronchial lesion (blue area).

     
    Area of Interest: Thorax; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;

    Area of Interest: Thorax; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;

    Expiratory study shows a circumscribed area of air trapping on lingula lobe due to the bronchial obstruction (blue area).
