[Cystic duplications of the cervical esophagus].

Cystic duplications in the cervical region are very rare. In most cases compression of the trachea leads to severe symptoms of respiration. Two cases of cystic duplication are described - a nine months old child and a newborn baby. In the first case the cyst was localized on the right side of the thyroid. Extirpation could be done without any complications. The operation on the second case was difficult. The tumor was localized between oesophagus and trachea rotating the larynx.
