Congenital laryngeal cysts are rare and can cause upper airway obstruction if they are misdiagnosed. We describe a case of large vallecular cyst diagnosed at 33 weeks of gestation. The purpose of an early diagnosis is to establish a careful perinatal management. If the airway is compromised, a multidisciplinary medical team is necessary to perform emergency immediate tracheostomy. Elective delivery should be always carried out in a tertiary referral center.
