| branchial cleft cyst | Also called a branchial cyst, this is a cavity that is a remnant from embryologic development present at birth in one side of the neck just in front of the large angulated muscle on either side (the sternocleidomastoid muscle).

Total surgical excision is the treatment of choice. Recurrence is not expected. (12 Dec 1998) |
