[Congenital vallecular cyst with weight disorders. Case report].

Vallecula cysts are a rare condition in children, with stridor being the most common symptom and growth alterations the more uncommon. We present a 2 months-old child referred by low weight gain from birth, with a history of choking when feeding. He had no respiratory distress but struck mouth breathing and neck hyperextension with lateralization to the right. The esophagogram showed a mass displacing hypopharynx and larynx reflux of contrast into the bronchial tree. The cyst was resected by direct laryngoscopy with marsupialization technique. The outcome was favorable, without recurrence until the fourth month of monitoring.
