A branchial cyst is also called branchial cleft cyst in children. If there are signs of infection, your doctor will prescribe antibiotics. Sometimes it is necessary to drain fluid from the cyst to ease swelling. To prevent future infections, surgery to remove the cyst is usually recommended. It is also important to exclude a metastatic lymph node as these can present similarly, particularly in people of 40 years of age or older.
