Laryngeal problems in the scimitar syndrome.

The scimitar syndrome is a congenital anomaly of the venous system of the right lung. This diagnosis is suspected when a scimitarlike shadow is found on the thoracic roentgenogram; the definitive diagnosis is made by angiography when an abnormal outflow of the venous system of the right lung is found. Dyspnea and recurrent infections are the most prominent clinical feature. In a child with the scimitar syndrome, a laryngeal anomaly was found that caused stridor from birth onwards. A right-sided arytenoidectomy was performed with relief of all the symptoms. The follow-up period has been two years.
