We report a 14-year-old male with acute suppurative thyroiditis originating in a right piriform sinus fistula. After he manifested anterior cervical swelling, he was found in computeded tomography and ultrasonography to have an abscess in the right thyroid lobe. He was treated with surgical drainage and antibiotics. Three months after treatment, pharyngoesophagography showed right piriform sinus fistula, which was resected cervically. No recurrence of acute suppurative thyroiditis has been seen in the 30 months since surgery.
Although right side piriform sinus fistula is relatively rare, it should be considered among the causes of acute suppurative thyroiditis or cervical abscess on the right side.
