  • Figure 1
    18F-FDG PET/CT images: at baseline (a), after treatment (b)
     

    Axial fused 18F-FDG PET/CT images. At baseline a high FDG uptake (SUV max 7.2) is present in the interatrial septum.

     
    Area of Interest: Thorax; Imaging Technique: PET-CT; Procedure: Diagnostic procedure; Special Focus: Lymphoma;

    Axial fused 18F-FDG PET/CT images. After 2 cycles of G-CHOP regimen no residual uptake is present.

     
    Area of Interest: Thorax; Imaging Technique: PET-CT; Procedure: Diagnostic procedure; Special Focus: Lymphoma;
     
     
  • Figure 2
    Cardiac MR images in four chamber view
     

    Cardiac MR images in four chamber view showed a mass in the interatrial septum with high signal on STIR (short inversion time recovery) T2-weighted images.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Lymphoma;

    Cardiac MR showed a heterogeneous late enhancement on contrast-enhanced cine balanced steady-state free precession (SSFP) sequences.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Lymphoma;

    Cardiac MR showed a heterogeneous enhancement on LGE images.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Lymphoma;

    After 2 cycles of G-CHOP, cardiac MR shows a residual thickening of the interatrial septum on STIR T2-weighted images.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Lymphoma;

    After 2 cycles of G-CHOP, cardiac MR shows a residual thickening of the interatrial septum on unenhanced cine SSFP sequences.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Lymphoma;

    After 2 cycles of G-CHOP, no residual enhancement was detectable on LGE images.
