Acute suppurative thyroiditis (AST) is a rare inflammatory disease of the thyroid gland. We reported AST in a 38-year-old female. She complained of painful swelling of the right anterior neck region. The pain developed after swallowing of a fish bone. CT showed a deep neck infection and we performed surgery. We could not detect a piriform sinus fistula, but we speculated that the neck infection was caused by swallowing the fish bone.
