case_images: Ultrasonography of the swelling showed an anechoic, bilobed fluid collection in left submandibular region with a superficial and deep component (Figure 2(a)). 1.0 ml of a water-based iodine contrast media was injected in left sublingual region and a lateral oblique projection of left submandibular region was made to view the extensions (Figure 2(b)). T-2 weighed MRI images, showed hyperintense fluid filled cavity in left sublingual space, extending to left submandibular space along the posterior edge of mylohyoid muscle (Figures 2(c) and 2(d)).
