A Rare Case of Coexistence Ectopic Lingual Thyroid and Thyroglossal Cyst with Tc 99 m Thyroid Scintigraphy

Lingual thyroid is a very rare anomaly and is usually incidentally found in patients that have hypothyroidism or mass in throat. This case however had another mass in the submandible with diagnosis of thyroglossal cyst. Thyroglossal duct cyst is the most common congenital neck mass. About 50% of cas...

Summary:Lingual thyroid is a very rare anomaly and is usually incidentally found in patients that have hypothyroidism or mass in throat. This case however had another mass in the submandible with diagnosis of thyroglossal cyst. Thyroglossal duct cyst is the most common congenital neck mass. About 50% of cases present before the age of 10 and second group age present in young adulthood. We present a 27-year-old man who presented with sub-mental mass. The patient had also hypothyroidism. A CT scan was performed to confirm the diagnosis. The CT scan confirmed submental cyst and incidentally discovered lingual thyroid along with absence of thyroid tissue in its normal pretracheal position. The patient had symptoms of hypothyroidism and he was treated with levothyroxin. Our case report highlights a rare and unusual situation because of the coexistence of a thyroglossal cyst and a partially functional lingual thyroid.
