What are symptoms of a branchial cyst?
Branchial cysts usually cause no immediate problem. They can cause a pressure sensation in the area affected. Sometimes it develops a sinus or drainage pathway to the surface of the skin from which mucus can be expressed. They are typically not tender. Rarely, however, they can become infected.
What are structures in the neck that can be similar to a branchial cyst?
There can be other structures in the neck area of a similar character. These include
- Cystic hygroma: This structure is a malformation of the lymphatic system in the neck region. The lymphatic system is composed of a series of vessels that drain a milky white liquid (lymph) that contains fluid and white blood cells for fighting infection. In comparison with a branchial cleft cyst, a cystic hygroma is also smooth and soft but is located behind the sternocleidomastoid muscle.
- Thyroglossal duct cyst: This structure commonly drains from inside the floor of the mouth to an opening similar to that of a branchial cleft cyst, but it's located in the center of the neck in the area of the larynx (voice box).
- Swelling of the thyroid gland: This soft structure has two lobes that are located on either side of the windpipe (trachea) at the level of the vocal cords. There is a thin connection of thyroid tissue that bridges the two lobes and crosses over the trachea.
- Miscellaneous: collections of fat (lipomas), collections of blood vessels (hemangiomas), sebaceous cysts, etc.
How is a branchial cyst treated?
Total surgical excision is the treatment of choice. Recurrence is not expected.
