이상와 누공(piriform sinus fistula)에 기인한 재발성 화농성 갑상선염 1예 : A Route of Infection in Recurrent Suppurative Thyroiditis = Piriform Sinus Fistula

다국어 초록 (Multilingual Abstract)

Piriform sinus fistula, believed as an embryonic remnant of the third or forth pharyngeal pouch, is an extremely rare and newly recognized entity that lead to acute suppurative cervical infection. Recently, reports of acute suppurative thyroiditis and anterior neck abscess due to piriform sinus fistula have been increasing in number, though an extensive review of the literature reveals that about 60 cases of this condition have been reported. The sinus may be overlooked for years and the patient may undergo multiple procedures before the diagnosis is properly made and treated. We have experienced such a case of recurrent suppuative thyroidits in which coexisting piriform sinus fistula was identified by intra-operative endoscopic examinaton. This report reviews the embryological development of the sinus and the clinical symptoms and treatment of this condition.
