Third or 4th branchial remnants are the rarest of branchial pouch anomalies. They are almost always left sided- as many of 97% of cases are on the left.
They may present as lateral neck swelling in a child or adolescent, or recurrent lateral cervical abscesses or recurrent lateral thyroiditis. CT may show a communication with the pyriform fossa, indicated that the lesion is in fact a sinus.
Treatment includes surgical removal or cauterisation with Trichloroacetic acid.
