title: Neonatal neck mass in identical twins: an unusual presentation.
abstract: Identical twins were noted to have a soft asymptomatic neck mass, each on the opposite side, at 1 week of age. The mass took a dramatic course 1 week later to present as a neck abscess, yet without systemic symptoms. Ultrasonography was highly suggestive of an infected lymphatic malformation (cystic hygroma). Intravenous antibiotics and drainage (aspiration/incision and drainage) resulted in resolution of the mass and no recurrence at 18 months follow-up. The concept of spontaneous involution of lymphatic malformation (cystic hygroma) is discussed as well as the management of neck abscesses in infancy.
