Cervical Adenitis

What is cervical adenitis?

Cervical adenitis is a bacterial infection of a lymph node in the neck. Lymph nodes are part of our immune system, which helps fight infections. Sometimes nodes in the neck become infected and these infections are called cervical adenitis. Children with the infection have a hard, painful, swollen mass in the neck and may have a fever.

Most lymph node infections heal well with oral antibiotics, but a few need to be opened and drained. Those that need to be drained become soft in the middle.

What is the cause?

Bacteria present in the nose, tonsils, or adenoids can spread to the lymph nodes and cause an infection. Also, cavities in the teeth can become infected and the bacteria may then spread to the lymph nodes. The infected lymph node then becomes enlarged, warm, and tender.

What is the treatment?

  • Oral antibiotics

    Antibiotics are used to treat the bacterial infection. Your child's antibiotic is ________________________. Your child's dose is _________ given ____ times a day for a total of ____ days.

    Your child needs to take the antibiotic as prescribed and not stop taking the medicine even if the symptoms are going away.

  • Fever and pain relief

    Give your child acetaminophen or ibuprofen if he or she develops a fever of 102°F (39°C) or higher or has pain from the neck swelling.

  • Fluids

    Make sure your child is drinking plenty of fluids.

  • Observation of lymph nodes

    Your child's lymph node may have been outlined with a pen during your visit. If so, watch to see that the node is not enlarging outside of the markings.

  • Follow-up visit

    All children with lymph node infections should see their doctor within 2 to 3 days of beginning treatment to make sure the lymph node is getting better.

When should I call the doctor?

Call IMMEDIATELY if:

  • You child has a new high fever of 102°F (39°C) or higher.
  • Your child has any difficulty swallowing liquids or breathing.
  • The lymph node is rapidly enlarging even though your child is taking oral antibiotics.
  • Your child starts to act very sick.

Call within 24 hours if:

  • The lymph node is becoming soft in the middle.
  • The swelling is enlarging after 48 hours of antibiotics and your child is not getting better.
  • You have other questions or concerns.
