Empyema and mediastinal abscess in pyriform sinus fistula: A case report / 世界急诊医学杂志（英文）

ABSTRACT

@#Though notorious for its tendency to induce recurrent neck abscess, pyriform sinus fistula is of importance despite its rarity. It usually presents diagnostic and therapeutic challenges. Because of post-infectious fibrosis, the embryologic origin of pyriform sinus fistula is difficult to appreciate in certain cases. Here we present a case with empyema and mediastinal abscess caused by pyriform sinus fistula and share our experience in the treatment of this patient.
