| Abstract |
|
Pyriform sinus fistula (PSF) is a persistent embryologic third or fourth pharyngeal pouch, which typically presents as a congenital sinus tract that originates from the pyriform sinus. PSF is among the most uncommon congenital malformation of the neck. The usual clinical manifestations are either acute thyroiditis or abscess, usually on the left side of the neck. We report a case of PSF in a 9-year old female with a left cervical abscess who had been diagnosed by barium esophagogram and treated endoscopically by injection of histoacryl. |
