male, 64 year(s)
 
 
  • Figure 1
    Chest radiographs
     

    A. Chest-X-ray previous to the unsuccessful pacemaker implantation.

     
    Area of Interest: Lung; Imaging Technique: Conventional radiography; Procedure: Catheters; Special Focus: Trauma;

    B. Apical and lateral pleural effusion (black arrows), as well as mediastinal thickening (black line) appeared in the control after the failed attempt.

     
    Area of Interest: Lung; Imaging Technique: Conventional radiography; Procedure: Catheters; Special Focus: Trauma;
     
     
  • Figure 2
    CT reconstructions showing the pleural collections.
     

    A. In a coronal CT reconstruction the black arrow marks the pleural effusion located in the left apex (black arrow)

     
    Area of Interest: Interventional non-vascular; Imaging Technique: CT-High Resolution; Procedure: Diagnostic procedure; Special Focus: Trauma;

    In B and C we can see other pleural collection in differents axial planes (white arrows).

    A. Coronal CT plane showing a well-defined saccular mass (black arrow) with an homogeneous enhancement.

     
    Area of Interest: Mediastinum; Imaging Technique: CT-High Resolution; Procedure: Diagnostic procedure; Special Focus: Trauma;

    B. Sagittal CT reconstruction in which the neck of the pseudoaneurysm can be distinguished (white arrow).

     
    Area of Interest: Mediastinum; Imaging Technique: CT-High Resolution; Procedure: Diagnostic procedure; Special Focus: Trauma;

    Another axial plane in which we can see the homogenous enhanced mass (black arrow), located in the prevascular mediastinum. The neck is also identified in this image.
