Midline posterior cervical cystic hygroma.South Med J. 1999 Mar; 92(3):340-3.SM
Cystic hygromas are among the most common congenital neck masses. They have a predilection for the left posterior triangle and manifest early in life. Although various locations of cystic hygromas are found in the literature, we believe our case of a 9-month-old girl represents the first reported occurrence of a posterior cervical midline cystic hygroma.
