Management of pediatric thyroglossal duct cyst: A case report

Introduction: Thyroglossal duct cysts are common congenital neck anomalies in children, diagnosed through clinical assessment and ultrasound, and treated with the Sistrunk procedure to prevent complications like infection and malignancy. Case Description: We present a case of a 4-year-old male patient with a progressively enlarging neck mass for three months. The mass was asymptomatic, did not cause any eating difficulties, and moved upwards during swallowing and tongue protrusion. Upon physical examination, a soft, mobile, cystic mass approximately 3 cm in diameter was identified beneath the hyoid bone. Supporting examinations, including ultrasound and fine-needle aspiration cytology, led to the diagnosis of a thyroglossal duct cyst. The patient underwent a successful Sistrunk procedure, which involved the excision of the cyst along with a portion of the hyoid bone. Postoperative management included administration of intravenous antibiotics and paracetamol, culminating in a full recovery without any signs of infection. The patient exhibited complete wound healing within two weeks. There was no evidence of cyst recurrence during a follow-up examination six months later. Conclusion: Despite being common, thyroglossal duct cysts require thorough evaluation to avoid misdiagnosis, and are typically identified by a slowly growing midline neck mass that moves with swallowing and tongue protrusion, often near the hyoid bone.
