A 10-YEAR-OLD white boy presented with an 8-year history of an enlarging mass in the right side of his neck. He initially presented at the age of 2 years with a mass in the right side of his neck that arose after an upper respiratory tract infection. The mass subsequently regressed, only to return 2 months later. A workup was negative for tuberculosis, and the mass again regressed after a short course of antibiotics. It reappeared within 2 months. Ultrasonography and computed tomography revealed a multicystic, multilobulated mass deep to the sternocleidomastoid muscle. The findings of fine-needle aspiration of the mass were not diagnostic. A presumptive diagnosis of a cystic hygroma was made, and it was decided that the patient's clinical progression should be observed.
