    Axial SE T1-weighted image shows a well-circumscribed right submandibular mass (T), heterogeneously isointense with the muscle, but also containing signal-void vascular structures.

     
    Area of Interest: unknown; Imaging Technique: Non-contrast studies;

    Axial FSE T2-weighted image shows the mass with heterogeneous intermediate-to-high signal intensity, splaying internal (closed arrowhead) and external carotid arteries (arrow), and displacing internal jugular vein...

     
    Area of Interest: unknown; Imaging Technique: Non-contrast studies;

    Sagittal FSE T2-weighted image shows the mass (T) with heterogeneous intermediate-to-high signal intensity, located above the carotid bifurcation (arrowhead)and splaying internal and external (arrow) carotid arteries.

     
    Area of Interest: unknown; Imaging Technique: Non-contrast studies;

    Coronal fat-suppressed FSE T2-weighted image shows the mass (T) with heterogeneous high signal intensity, located above the carotid bifurcation (arrowhead). Note internal carotid artery (arrow) is displaced posteriorly.

     
    Area of Interest: unknown; Imaging Technique: Non-contrast studies;

    Contrast studies
     

    Axial post-gadolinium SE T1-weighted image shows the marked contrast enhancement of the mass (T), with vascular structures within the stroma.

     
    Area of Interest: unknown; Imaging Technique: Contrast studies;

    Sagittal post-gadolinium SE T1-weighted image shows the marked contrast enhancement of the mass (T), with vascular structures within the stroma.Note anteriorly displaced external carotid artery (arrow).

     
    Area of Interest: unknown; Imaging Technique: Contrast studies;

    Coronal post-gadolinium SE T1-weighted image shows the marked contrast enhancement of the mass, with vascular structures within the stroma.

    MR angiography studies
     

    Sagittal oblique view of MR angiography reveals splaying of the internal (I)and external (E)carotid arteries by the mass.

     
    Area of Interest: unknown; Imaging Technique: MR angiography studies;

    Axial view (from the top) of MR angiography reveals splaying of the internal and external carotid arteries by the mass.
