Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection. We present a case of a 13-year-old female patient with a pyriform sinus fistula that caused a deep infection of the left side of the neck and showed double-tract involvement discovered during surgical resection of the entire fistula. Both tracts arose around the pyriform sinus and terminated at the upper portion of the left lobe of the thyroid.
梨状窝瘘是一种罕见的临床病症，其确切起源仍存在争议。该瘘管在患有急性化脓性甲状腺炎或左侧颈部深部感染的患者中被发现，通常位于左侧梨状窝。据我们所知，仅有单一管道被报道与梨状窝瘘感染有关。我们报告一例13岁女性梨状窝瘘患者，该瘘管导致左侧颈部深部感染，在整个瘘管手术切除过程中发现存在双管道受累情况。两条管道均起于梨状窝周围，止于甲状腺左叶上部。
