[Piriform sinus fistula resulting in acute dyspnea in a newborn]. / Sinus-piriformis-Fistel als seltene Ursache von Dyspnoe bei einem Neugeborenen.

ABSTRACT

Piriform sinus fistulas are rare congenital deformities that may become symptomatic through cyst enlargement and inflammation. The fistula usually manifests as bacterial thyroiditis and is very uncommonly seen as a cause of acute dyspnea in newborns. We report the case of a newborn in whom a piriform sinus fistula led to acute breathing impairment. If the piriform sinus fistula and adherent cyst cannot be totally removed initially, the treatment must be followed later by a complete resection to prevent infection.
