Huge Thyroglossal Duct Cyst Mimicking As Goiter In An Adult Man

Abstract

Thyroglossal duct cyst is the most common congenital cervical mass found mainly in children but only 7% of them are among adult population. They are mostly asymptomatic and found around the region of hyoid bone. Their size usually varies around 1.5 to 3cms. but cases are reported with unusually larger sized cysts, which may cause pressure symptoms over upper aero-digestive tract. We are reporting a case of unusually huge thyroglossal cyst of size of 6 x 8 cms in a 26- year-old man. This cyst was not apparent at time of birth or in early childhood but appeared later on. Initially it was very small but progressively and gradually increased to its present size. On first look, it appeared as thyroid swelling with soft to firm in consistency but on examination it was moving with both deglutition and tongue protrusion. Ultrasonography and CT scan of the neck confirmed the diagnosis of thyroglossal cyst. Thyroid scan showed, thyroid gland in its normal position. Sistrunk’s operation was done with a midline vertical incision and the subsequent recovery was uneventful
