Lingual thyroid diagnosis

The thyroid scan with computed tomography (CT) confirmed the diagnosis of lingual thyroid. Because of the clinical presentations and imaging results, a presumptive diagnosis of ectopic lingual thyroid was impressed. Normal thyroid function tests were confirmed. Ultrasound-guided fine needle aspiration (FNA) was performed for the tumor, and the. The diagnosis and management of lingual thyroid is discussed. All patients need lifelong thyroxine suppression. Unenhanced computed tomographic scans have a diagnostic appearance due to the iodine content of the ectopic thyroid tissue. (Arch Intern Med 1987;147:2046-2048) Full Text Six cases of lingual thyroid were discovered in five females and one male, ranging in age from 5 to 26 years. Four were noted during thyroglossal duct surgery, one because of a mass in the vallecula, and one incidentally found during a workup for possible hyperthyroidism. Only one patient was known to have a lingual thyroid preoperatively

It may present with symptoms of dysphagia, upper airway obstruction, or even hemorrhage anytime from infancy through adulthood Findings were consistent with a diagnosis of lingual thyroid. Dimensions of lingual thyroid tissue of 1.9cm·1.7cm·2.4cm (calipers have 1cm gradations) resulted in a calculated volume of 4.1g of glandular tissue. The 24-hour 123I thyroid uptake was measured at 10.3%.

The objective of this article is to report a rare case of lingual thyroid, its presentation, diagnosis, and management Lingual thyroid is an ectopic thyroid which is an embryological abnormality that results from the failure migration of the thyroid gland from the primitive foregut to the normal thyroid position at the neck Ectopic thyroid gland at the base of the tongue, referred to as lingual thyroid, is a rare congenital anomaly resulting from the incomplete descent of the gland during embryogenesis. 1 The prevalence of lingual thyroid is reported as 1:100 000-1:300 000 and it is seven times higher in females. 2 Treatment depends on the clinical presentation. . Asymptomatic patients require thyroxine. Lingual thyroid tissue is associated with an absence of the normal cervical thyroid in 70% of cases. It occurs much more commonly in women than in men. The diagnosis is usually made by the discovery of an incidental mass on the back of the tongue in an asymptomatic patient (Fig. 96-20)

A cyst at the base of the tongue was suspected, but additional examination showed that it was an ectopic thyroid tissue marked as a lingual thyroid gland.

Conclusion: Management of patients with LT should be individualized and guided by the patients symptoms and thyroid hormone status. (Endocr Pract. 2016;22:343-349) AB - Objective: Lingual thyroid (LT) results from a developmental abnormality due to failure of the thyroid gland to descend to its pretracheal position In 70% of cases the lingual thyroid is the only functional thyroid tissue, leading to the commonality of accompanying hypothyroidism in patients. [4] The mean age of diagnosis for lingual thyroid is 40 years old, with statistical peaks at 12.5 and 50 years, [5] with a strong female predominance. [6 Although magnetic resonance imaging (MRI) may provide a diagnosis of lingual thyroid , its clinical usefulness in the diagnosis of patients with CH has not been evaluated. Color Doppler ultrasonography (CDU) provides not only the standard gray-scale image, but also a color display of blood flow and, hence, permits the evaluation of thyroid.

Hickmann recorded the first case of lingual thyroid in 1869 Less commonly, a thyroid will grow downward rather than up and out within the neck.
