Ethanol Ablation of a Thyroglossal Duct Cyst and Review of the Literature.

Abstract

Ultrasound-guided ethanol ablation (EA) is a less invasive alternative to surgical resection for the management of thyroglossal duct cysts (TGDCs). However, to date, EA is rarely used in the United States to treat TGDCs. We present a case of TGDC successfully treated with EA in the United States. A 66-year-old man presented with a mobile anterior neck mass. Neck ultrasonography revealed a complex cystic mass in the midline directly anterior to the trachea, measuring 52 × 41 × 50 mm. Fine needle aspiration revealed no malignant cells, and pathology was consistent with TGDC. The patient had no contraindications to surgical resection. The patient's pretreatment symptom score was 7 and cosmetic score was 3. One month after EA, volume reduction ratio was 40%, symptom score was 1, and cosmetic score was 3. Four months after EA, the TGDC was resolved without need for an additional procedure. The volume reduction ratio was 96.8%, and symptom score and cosmetic score were both 1. In summary, EA is a viable alternative to surgical resection, even in patients who are surgical candidates. EA is attractive due to its simplicity, cost effectiveness, and tolerable side effect profile. Further studies are needed to evaluate long-term safety and efficacy, particularly in United States patients.
