Patient
female, 54 year(s)
 
 
  • Figure 1
    Multislice computed tomography showed lipomatosis of the interatrial septum

    MSCT images show typical waist in fatty mass at the level of the fossa ovalis, producing a dumbbell shape and wedge-shaped lateral part. After intravenous administration of contrast agent, there is no enhancement.

     
    Area of Interest: Cardiac; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 2
    Cardiac MRI T1

    An ECG triggered breath hold turbo spin echo sequence in a four chamber view is shown. The atrial septum is thickened. The signal of the septum thickening is typically isointense to the subcutaneous fat.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 3
    Cardiac MRI Fat saturation

    CMRI fat saturation images show the signal from atrial septal lipomatous hypertrophy is "nulled", confirming its fatty composition.

     
    Area of Interest: Cardiac; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Tissue characterisation;
     
     
  • Figure 4
    Multislice computed tomography

    MSCT coronal image shows mild compression of the inferior vena cava.
