title: Recurrent suppurative thyroiditis due to pyriform sinus fistula: a case report.
abstract: Acute suppurative thyroiditis is a rare disease, particularly in childhood. We present a case with recurrent acute suppurative thyroiditis due to a pyriform sinus fistula originating from the fourth branchial pouch. The typical symptoms of a pyriform sinus fistula are recurrent left-sided pain and swelling of the neck with signs of acute bacterial inflammation. Diagnosis should be made by high resolution ultrasound, barium meal studies and endoscopic examination. During acute exacerbations treatment with antibiotics is indicated, but permanent cure can only be attained by complete fistulectomy.
