First Branchial Cleft Cyst-CT

First branchial cleft cyst are of two types--Type I cysts are located near the external auditory canal. Most commonly, they are inferior and posterior to the tragus (base of the ear), but they may also be in the parotid gland or at the angle of the mandible. Type I cysts may be difficult to distinguish from a solid parotid mass on clinical examination. Type II cysts are associated with the submandibular gland or found in the anterior triangle of the neck. Thin capsular enhancement is noted on post contrast scans.
