Figure 6: Head and neck magnetic resonance imaging: axial T2 MRI revealed enlargement of the lateral rectus muscle of right orbit (arrows) (a). A coronal contrast-enhanced T1 MRI showed an infiltrating lesion centered in the right masticator space extending into the submandibular space involving the submandibular gland. Note the avid gadolinium enhancement pattern of the lesion and its ill-defined margins (b).
