Lymphatic malformation (LM) in a term-born-boy presenting with a large anterior and lateral neck mass beneath a bluish-coloured skin. a Ultrasound of the neck shows that the mass is composed of large fluid-filled macrocystic (asterisk) and microcystic (arrowheads) portions. b Sagittal T2 illustrates the macrocystic submental component extending into the base of the tongue (arrow). Percutaneous sclerotherapy was carried out. Post-sclerotherapy follow-up MRI (c, d). c Axial T2 depicts intracystic fluid/fluid levels due to internal bleeding (arrows). Fat-saturated, contrast-enhanced T1 (d) shows enhancement of the thin septae of the macrocystic and microcystic components. Two years later, the mandibular deformation is visible on the follow-up MRI (T2W image, e, arrowheads) and on an x-ray image (f, arrows), obtained during percutaneous sclerotherapy (asterisk)
