Air-filled cyst in the neck: The only documented sixth branchial anomaly.

There are various congenital anomalies of branchial origin found in the neck region. This paper reports a case of a right anterolateral cervical air-filled cyst in a 47 year-old female. Several radiologic studies were done to establish a possible connection with the digestive and respiratory tracts. Differential diagnoses such as branchial cyst, laryngocele, a bronchogenic cyst or a pneumatocele were entertained. Subsequent neck exploration revealed a cyst with a sinus tract leading into the right apical pleura. Histopathologic examination showed findings consistent with a branchial cyst. It is, therefore valid to conclude that this is a cyst originating from the sixth branchial arch, the recurrent laryngeal nerve. This is perhaps the first and only documented case of such an anomaly in world literature.
