Huge thyroglossal duct cyst at the supra-sternal notch

Abstract

Thyroglossal duct cysts (TGDC) are the most common congenital cysts in the neck. TGDC typically present as a midline swelling anywhere between the foramen cecum and the isthmus of the thyroid gland. Majority occurs just below the hyoid bone and those descending below the thyrohyoid membrane are rare. TGDC are usually less than 3 cm in diameter while big cysts are uncommon. We present a 19 years old female patient who presented with giant (12 cm diameter) supra-sternal notch cyst which was diagnosed as TGDC only after histopathology. The rarity of such huge TGDC in such uncommon site, which was misdiagnosed as a retention cyst (Mucocele) made us report this case.

Large Thyroglossal Duct Cyst Presenting in Adulthood: A Case Report and Literature Review

“…In this case report, our patient presented with an atypical clinical course in terms of the adult age of onset and large cyst size. Several large TGDC cases in adults have been highlighted in the literature [6][7][8][9][10][11][12][13][14][15]. Due to its rarity, most of the literature was case reports.…”

“…Having said that, Baisakhiya and Abebe et al described large TGDC > 10 cm without compressive symptoms. Thus, no peri-operative measures were taken [ 14 , 15 ]. Similarly in our case, the pre-operative laryngoscope performed did not reflect any sign of airway compromise or compression of the pharyngeal wall from the mass effect of the anterior neck swelling.…”

Large Thyroglossal Duct Cyst: A Case Report

“…Ramalingam reported a case of an adult with a cystic neck mass measuring 8×7 cm on physical examination [11]. Larger cysts have also been reported, measuring 12 cm [12] and a giant one at 30×24 cm [13] in a patient with schizophrenia. All patients underwent a Sistrunk procedure and had an uneventful recovery.…”

Thyroglossal Duct Cyst, a Case Report and Literature Review

“…We included all ten remaining publications in this analysis and thoroughly reviewed and analyzed them (see Figure 1). A total of 46 patients (excluding our patient) were studied with regard to the mass characteristics, treatment, and clinical outcome based on the 10 preselected studies [6][7][8][9][10][11][12][13][14][15]. Including our case, the study sample, therefore, included 25 males (53.1%) and 21 females (44.7%), along with one case of unknown gender (2.1%).…”
