Imaging findigns in lingual thyroid: Apropos or two cases

Lingual tiroid, tiroid bezinin kısmi ya da tam göç etmemesine bağlı ortaya çıkan gelişimsel bir anomalidir. Olguların çoğunda lingual tiroid tek işlev gösteren tiroid dokusudur. Bu nedenle tanısı, cerrahi sonrası kalıcı hipotiroidizmin önlenmesi açısından önemlidir. Lingual tiroidin görüntüleme bulguları literatürde bildirilmiş olup en sık tanımlanan dil kökünde düzgün konturlu kontrast tutulumu gösteren kitle lezyonu şeklindedir. Amacımız bu nadir gelişimsel anomalide karşılaşılabilecek geniş radyolojik bulgu spektrumunu iki olgu ile vurgulamaktır.

Lingual tiroidde görüntüleme bulguları: İki olgu sunumu

Lingual thyroid is a developmental anomaly caused by undescended thyroid tissue at the base of the tongue. In the majority of patients., the lingual thyroid is the only functioning thyroid gland tissue. Therefore early diagnosis with imaging techniques is clinically important to avoid permanent hypothyroidism following surgical removal. Imaging findings of this entity have previously been reported. Although varying degrees of contrast enhancement have been described, the most frequent presentation is a smoothly shaped enhancing mass at the base of the tongue. We present two cases of lingual thyroid in order to emphasize the wide spectrum of radiological findings encountered in this rare developmental anomaly.
