male, 84 year(s)
 
 
  • Figure 1
    Figure 1- Balanced FFE axial image

    Evidence of a solid, lobulated mass of 8,2x7,6x9 cm, strictly adjacent to the right atrium wall, that is enlarged. Bilateral pelural effusion and pericardial effusion are also present.

     
     
     
  • Figure 2
    Figure 2 a, b- Axial T2 weighted FSE image (a), T1 GE image post Gagolinium administration (b)

    The mass appeared hyper-intense on T2 weighted and presented increasing enhancement on T1 weighted sequence post Gadolinium administration

     
     
     
  • Figure 3
    Figure 3 a, b- Balanced FFE on axial plane

    Inferior vena cava partially compressed by the mass (a) and superior vena cava obstructed by a endoluminal thrombus (b).

     
     
     
  • Figure 4
    FIgure 4- T1 weighted GE axial image post Gadolinium administration

    A necrotic lymph node was present next to the inlet of the inferior vena cava in the right atrium (white ROI).

  • Figure 6
    Figure 6 (a, b)- Histologic section from the mass

    HIstologic section of the mass showing large abnormal cells with irregular nuclei. Hematoxylin and eosin stain 10X (a). Positively stained for CD 20 antigen 10X (b).

     
     
     
  • Figure 7
    Figure 7- CTs follow-up

    3 months follow-up CT (a) and 6 months follow-up CT (b) showing volumetric reduction of the mass.
