SANTAS ALEGRET, Mario et al. Fourth branchial cleft cyst. Case report and bibliographic review. Rev Esp Cirug Oral y Maxilofac [online]. 2021, vol.43, n.3, pp.105-108.  Epub 25-Out-2021. ISSN 2173-9161.  https://dx.doi.org/10.20986/recom.2021.1163/2020.

Fourth branchial cleft anomalies are extremely rare and usually present as asymptomatic cervical masses or recurrent neck infections. Diagnosis is made with an adequate anamnesis, physical examination and imaging tests. Complete surgical resection of the mass is the gold standard treatment to minimize the chance of recurrence.

We report a case of a newborn with a fourth branchial cleft cyst presented as an asymptomatic left-sided neck mass. Diagnosis was made with ultrasonography and mangnetic resonance imaging and confirmed histologically after the patient was surgically treated.
