Ectopic lingual thyroid with vascular anomalies

Abstract

BackgroundLingual thyroid represents 90% of ectopic thyroid tissue localizations. The first case was described by Hickman in 1869. An ectopic thyroid is often asymptomatic, but pathological or physiological conditions inducing hyperproduction of thyroid-stimulating hormone can lead an ectopic thyroid to become symptomatic. Treatment of the symptomatic ectopic thyroid can be medical, with hormone-suppressing therapy, or surgical.Case presentationA 17-year-old female presented to our outpatient clinic complaining of a sensation of a lump in her throat. Ear, nose, and throat (ENT) examination identified a swelling of the base of the tongue in the glossoepiglottic area. Thyroid scintigraphy showed a single contrast enhancement in the sublingual region, instead of in the normal anatomical position of the thyroid. She was treated surgically after failed hormone-suppressing therapy. An arteriography performed before the surgery showed vascular anomalies and was useful in surgical planning.ConclusionRecognition of vascular anomalies in an ectopic thyroid is fundamental before surgical planning, therefore, accurate radiological study of the vasculature should always be planned before surgical treatment of this disease.

“…it may cause problematic intubation or pose an increased risk of perioperative haemorrhage. Bianco et al suggested that arteriography before surgical removal of ectopic thyroid is performed, which might be useful in determining the presence of potential accompanying vascular abnormalities, thereby facilitating the procedure [54]. Another option is transposition of a lingual thyroid to the submandibular region, which was reported in a 52-year-old patient presenting with progressive obstructive symptoms.…”
