Type III Second Branchial Cleft Cyst: A Rare Presentation

Abstract

The second branchial cleft cyst (BCC) is the most common type of BCC. Bailey proposed a classification of the second BCC into four types, among which a Bailey type II cyst is the most common presenting lateral to the carotid space. A Bailey type III cyst, which extends between internal and external carotid arteries is an extremely rare occurrence. Complete surgical excision is the treatment modality of choice for branchial cysts and this warrants thorough imaging to see the detailed extent of the cyst. Contrast-enhanced computed tomography and Magnetic resonance imaging, both aid in diagnosis. Here we report a rare case of Type III second BCC, which presented with dysphagia, along with an elaboration of findings on imaging and treatment details.
