  • Figure 1
    Chest Radiograph

    PA view shows nodular and hazed infiltrates with honeycombed changes in both upper lobes, likely tuberculous changes, with possible bronchiectasis and volume loss in the right upper lobe. The right hemidiaphragm is...

     
    Area of Interest: Lung; Imaging Technique: Plain radiographic studies; Procedure: Diagnostic procedure; Special Focus: Infection; Neoplasia;
     
     
  • Figure 2
    Ultrasound

    Sonogram of the hepatic region shows a large heterogeneous iso- to hyperechoic lesion (arrow) above the right hemidiaphragm (*). Color Doppler study shows no increased vascularity.

     
    Area of Interest: Lung; Mediastinum; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    CT Scan
     

    Axial image shows a large, heterogeneously-enhancing lobulated mass (arrow) at the right side of the posterior mediastinum. Non-enhancing areas are appreciated within which may represent necrosis or hemorrhage. No...

     
    Area of Interest: Mediastinum; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Diagnostic procedure; Special Focus: Neoplasia;

    This large mass from the level of T8 to L3 causes significant mass effect seen as inferior displacement of the right hemidiaphragm (arrow), kidney, adrenal gland and bowel segments.

PA view shows nodular and hazed infiltrates with honeycombed changes in both upper lobes, likely tuberculous changes, with possible bronchiectasis and volume loss in the right upper lobe. The right hemidiaphragm is scalloped.
 
Sonogram of the hepatic region shows a large heterogeneous iso- to hyperechoic lesion (arrow) above the right hemidiaphragm (*). Color Doppler study shows no increased vascularity.
 
Axial image shows a large, heterogeneously-enhancing lobulated mass (arrow) at the right side of the posterior mediastinum. Non-enhancing areas are appreciated within which may represent necrosis or hemorrhage. No calcification is noted.
 
This large mass from the level of T8 to L3 causes significant mass effect seen as inferior displacement of the right hemidiaphragm (arrow), kidney, adrenal gland and bowel segments.
