Ectopic Lingual Thyroid, Le van Tai, Nguyen Thien Hung, Medic Medical Center, HCMC, Vietnam


We report the case of a 36 year-old female patient who presents with symptoms of dysphonia (hot potato speech) due to abnormal mass at the base of the tongue. Ultrasound detects no thyroid gland at the normal site. At the base of the tongue, there is an hypoechoic mass without hypervascularity on color Doppler, which is suspected for ectopic thyroid tissue. Then Tc99m sodium pertechnetate scanning shows thyroid tissue at the base of tongue and there is no thyroid tissue in the normal location.
