Thyroglossal Duct Cyst - An Observational Study from Visakhapatnam, Andhra Pradesh

BACKGROUND Thyroglossal duct cyst is a developmental cyst that occurs in 7 % of the population. These cysts are most commonly seen in paediatric patients. They occur due to failure of thyroglossal duct to involute and atrophy. Majority of them are found in infrahyoid region. The purpose of this research was to summarise our three years of clinical experience in different features of thyroglossal cysts and their surgical results, with an emphasis on the naked eye extent of a patent thyroglossal duct if present. METHODS This observational study was carried out in the Department of ENT, GVP IHC & MT – Visakhapatnam district, Andhra Pradesh for a period of three years from January 2016 to 2019. In our study, twenty patients were enrolled. Patients with cysts were initially diagnosed based on medical history, clinical examination, and ultrasound sonography (USG) reports. RESULTS Patients' clinical and surgical data, including cyst size and position, presence or absence of the thyroglossal duct, and so on, were analysed. The average age was 11 years. The majority (73.5 percent) were under the age of 15. Males accounted for 75 percent of the population, while females accounted for 25 %. Midline neck swelling was found in most of the patients (95 %). Majority (84.5 %) of cysts were located in the sub-hyoid region. Erythema over swelling was seen in 14.5 % of patients. Thyroglossal ducts were found to be patent at various lengths and areas. Majority of patients (75 %) had tract that began from cyst and ended at superior border of hyoid body while two patients (10 %) had patent thyroglossal duct from the cyst to the vallecular mucosa. Majority (70 %) cysts had size between 1.6 cm and 3 cm. Intraoperatively 15 % of cyst got ruptured. Most of them were present with visible midline neck swelling. None of the cysts had malignant characteristics in our study. CONCLUSIONS In most cases, a patent duct just disappeared at the superior border of body of hyoid. Complete patent thyroglossal duct from cyst to tongue musculature was rare. None of the cysts had malignant characteristics in our study. KEYWORDS Thyroglossal Cyst, Neck Swelling, Thyroglossal Duct

Thyroid Development

Thyroglossal duct cysts are most common congenital anomalies in thyroid development and are usually presented with midline neck swelling. The co-existence of carcinoma in thyroglossal duct cyst’s is extremely rare. We, herein present a case of primary papillary carcinoma arising from thyroglossal duct cyst in a 45 year old woman.

Ectopic Tissue

Background: The ectopic thyroid tissue in thyroglossal cyst or suprahyoid swelling is one of most important differential to be diagnosed. The purpose of this study was to find out role of Technetium-99m Pertechnetate Thyroid Scintigraphy (TS) to detect functioning thyroid tissue in ectopic locations presenting as midline neck swelling.Methods: A retrospective observational study was done where 26 subjects presenting with midline neck swelling were included. These subjects were injected with 1-5MBq/kg of Technetium-99m Pertechnetate to perform the TS. The uptake of tracer in the midline neck swelling and in other ectopic location was assessed. The comparison with Ultrasound (USG) was also done.Results: 12 (46.15%) subjects presented with infra hyoid swelling and rest 14 (53.85%) presented with supra hyoid and submental swelling. 33.3% subjects presenting with thyroglossal duct cyst showed functioning thyroid tissue. Also 4 subjects showed dual functioning ectopic tissue. USG an TS showed concordant results for detecting thyroid tissue in ectopic location (p=0.68). However, TS performed better to detect ectopically located thyroid tissue (p=0.0086).Conclusions: USG and TS showed similar results to detect thyroid tissue in normal location. However, TS is better to detect topically located thyroid tissue. TS adds information of functioning thyroid tissue during workup of midline neck swelling.

Ectopic Thyroid Tissue

Thyroglossal duct cysts are typically benign and usually asymptomatic. Malignant transformation is uncommon. Intralaryngeal extension is rare and results in dysphonia or dyspnea. There is no literature nowadays reporting the thyroglossal duct cyst carcinoma combining the clinical features of intralaryngeal extension. The authors present a case of progressive hoarseness and midline neck mass for 2 years. The laryngoscope and computed tomography revealed a 6-cm thyroglossal duct cyst containing ectopic thyroid tissue with intralaryngeal extension and causing airway obstruction. Complete excision with Sistrunk operation revealed papillary thyroid carcinoma. The patient resumed normal phonation after the surgery. There was no evidence of tumor recurrence and no hoarseness or dyspnea at 6 months follow up. This is the first reported case of a huge thyroglossal duct cyst carcinoma with intralaryngeal extension causing airway compromise. Complete excision of tumor is essential and vital to the symptom relief. A thyroglossal duct cyst carcinoma with endolaryngeal involvement should be considered in the differential diagnosis when the case has a massive midline neck mass with ectopic thyroid tissue and develops dyspnea or hoarseness concurrently.
