  • Figure 1
    Chest x-ray

    Frontal chest x-ray showing a posterior mediastinal mass on the left. It is seen in the left paravertebral region, and has a smooth outline.(marked)

     
    Area of Interest: unknown; Imaging Technique: Chest x-ray;

    Axial non-contrast CT of the chest

    Axial CT of the chest at the level of the carina showing a soft tissue mass in the posterior mediastinum. There is some rib moulding but no CT evidence of bony destruction. The mass is closely related to the...

     
    Area of Interest: unknown; Imaging Technique: Axial non-contrast CT of the chest;
     
     
  • Figure 3
    MRI of the chest
     

    Coronal T2-weighted image showing the mass lying just lateral to the spine. The mass has a high T2 signal.Once again there is no evidence of bony destruction. The mass is smooth.

     
    Area of Interest: unknown; Imaging Technique: MRI of the chest;

    Sagittal T1-weighted image showing an intermediate signal mass in the paraspinal region. The mass is well defined.

     
    Area of Interest: unknown; Imaging Technique: MRI of the chest;

    Axial T2-weighted image showing the paraspinal high signal mass. It is well defined and appears smooth.

     
    Area of Interest: unknown; Imaging Technique: MRI of the chest;

    T1-weighted sagittal image showing the relationship to the intervertebral foramen.

     
    Area of Interest: unknown; Imaging Technique: MRI of the chest;

    MIBG scan

    Posterior view from an MIBG scan showing increased activity in the left paraspinal region. This is 98% specific for this diagnosis.

Axial CT of the chest at the level of the carina showing a soft tissue mass in the posterior mediastinum. There is some rib moulding but no CT evidence of bony destruction. The mass is closely related to the descending thoracic aorta anteriorly and lies in line with the sympathetic chain.
