ABSTRACT
The parents of an 8-year-old boy are concerned about swelling to both sides of his neck. They initially noticed the swelling one month ago and they have increased in size. They noted drainage today. He has been acting well and eating normally. There is no fever, change in voice, or drooling. The parents do not recall a history of fall or trauma to the neck. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429435003/2bb12154-e53e-46cc-a47b-000836900a25/content/ufig173_1.jpg"/> https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429435003/2bb12154-e53e-46cc-a47b-000836900a25/content/ufig173_2.jpg"/>
