A Case of Piriform Sinus Fistula Complicated with Suppurative Thyroiditis Treated with Chemocauterization Using Trichloroacetic Acid / 계명의대학술지

ABSTRACT

A 23 months-old girl visited the hospital because of fever and left neck mass. She was diagnosed as acute suppurative thyroiditis with piriform sinus fistula. Thyroid sonography showed perithyroidal abscess formation and thyroid scan showed decreased uptake of Tc-99m pertechnate of both thyroid glands. Magnetic resonance imaging of neck showed abscess cavity extending to the swollen left thyroid gland. And there was tiny fistula between thyroid and piriform sinus in the barium esophagogram. Streptococcus gordonii was isolated on needle aspiration culture. We report a case of piriform sinus fistula of the neck complicated with suppurative thyroiditis. The fistula was treated with chemocauterization using trichloroacetic acid.
