Patient
male, 65 year(s)
 
 
  • Figure 1
    Chest X-ray

    Frontal radiogram displays cardiomegaly and a large rounded left perihilar mass.

     
    Area of Interest: Lung; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Aneurysms;
     
     
  • Figure 2
    CT coronal image

    CT coronal image shows a 6 x 7 cm low-density rounded mass on the left side of the middle compartment of the mediastinum.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms;
     
     
  • Figure 3
    Axial CT images

    Axial CT images show the extension of the mediastinal mass from the level of the aortic arch to the level of left atrium. Extensive calcification of the native coronary arteries is also seen.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms;
     
     
  • Figure 4
    Contrast-enhanced axial CT

    Contrast-enhanced axial CT shows partial filling of the lesion and connection between a vascular branch (graft) arising from the ascending aorta and the left circumflex coronary artery.

     
    Area of Interest: Cardiovascular system; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms;
     
     
  • Figure 5
    Contrast-enhanced axial CT

    Contrast-enhanced axial CT reveals contrast surrounded by low-density in keeping with thrombus. The mass is seen abutting the main and left pulmonary artery.
