We report herein on a case of a fishbone foreign body which had migrated through the thyroid. A 77-year-old female noticed a sore throat after she had eaten snapper for dinner. She visited at our hospital the same night, because the symptom did not improve after swallowing cooked rice. No foreign body was observed in the pharyngeal cavity. However, CT imaging revealed the presence of foreign body in the thyroid gland. As the foreign body was close to the common carotid artery, the foreign body was removed with a external incision in the neck. It is very rare for a foreign body to migrate through the thyroid gland. When encountering any such case, the clinician needs to select the extraction method carefully.
