Congenital Laryngeal Cyst: A Rare Cause of Stridor in Children

Abstract

Background: Congenital laryngeal cyst (CLC) is a rare cause of stridor in children. Objective: To describe the clinical profile of atypical stridor due to CLC.

Case report: A healthy infant was admitted for acute dysphonia, stridor and progressive respiratory distress without previous respiratory infection. A nasofiberoptic evaluation showed a laryngeal ventricle and a left aritenoepyglotic mass. The scanner revealed a unique CLC. A marsupialization was performed with resection of the walls. She had a successful ambulatory assessment of 3 months.

Conclusion: CLC causes an atypical stridor that requires a high suspicious index. Under special situations, an airway evaluation should be considered as essential for the management.
