title: Recurrent acute suppurative thyroiditis due to pyriform sinus fistula in an adult--case report.
abstract: We present a case study of acute suppurative thyroiditis (AST) with frequent recurrence due to anatomical malformation described as pyriform sinus fistula (PSF). Difficulty in diagnosis and treatment may be explained by the rarity of the disease in adult patients. AST had been observed in our patient five times before a radical surgery treatment was performed. The most typical symptoms and signs in our patient include: fever, difficulty in swallowing and tender tumour in the left side of the neck. Computed tomography (CT), barium swallow study and endoscopic examination gave us an opportunity to confirm the presence of an anatomical abnormality. After fistulectomy, we have not observed AST up to the date of this publication.
