Patient
female, 27 year(s)
 
 
  • Figure 1
    Trans-oral sonography of the tip of the tongue
     

    Sonography with 15 Mhz sound revealed an hypo-echoic mass, with thick walls and an “angioma like” Doppler pattern.

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: Ultrasound; Procedure: eLearning; Special Focus: Swallowing disorders;

    Sonography with 15 Mhz sound revealed an hypo-echoic mass, with thick walls and an “angioma like” Doppler pattern.

     
    Area of Interest: Ear / Nose / Throat; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Observer performance; Special Focus: Swallowing disorders;
     
     
  • Figure 2
    T1-weighted images

    Axial (A) and coronal (B) T1-weighted images showed an iso-intense mass at the left paramedian tip of the tongue

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Swallowing disorders;
     
     
  • Figure 3
    T2-fat sat weighted images

    Axial (A) an sagittal (B) T2-fat sat weighted images showed a homogeneous hyper-intense mass.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Swallowing disorders;
     
     
  • Figure 4
    T1-weighted images with gadolinium contrast

    Axial (B) and coronal (A) T1-weighted images with gadolinium contrast showed a centripetal, angioma-like enhancement with peripheral enhancement in the early phase (A) and complete homogeneous enhancement in the...

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Swallowing disorders;
     
     
  • Figure 5
    HASTE sequence

    Diffusion weighted (HASTE) sequences showed no restriction of diffusion.
