Overview

Introduction: Some extrathyroidal cervical cystic lesions can be treated in selected situations by minimally invasive, low-risk method – ultrasound-guided percutaneous ethanol injection therapy (US-PEIT). Here we present 6 cases of neck cysts of various origins – ranula, thyroglossal duct cyst, branchial cleft cyst, midline neck cyst of the pyramidal lobe and dermoid cyst. Method and material: The cohort consisted of 6 patients (mean age 58 ± 13.3 years), who were followed for recurrent cervical cysts located outside the thyroid gland. The cysts were visible, palpable, aesthetically unpleasant and also mechanically compressing the surrounding tissue. After repeated evacuations, they filled in again. The patients repeatedly refused the recommended surgery and demanded an alternative solution. US-PEIT of thyroid cysts is used worldwide as a full-fledged alternative to surgical treatment. We used the same procedure for the treatment of presented neck cysts. Results: The initial volume of cysts was 2–35 mL (mean 17.7 mL); the patients underwent 1–6 sclerotization sessions (mean 3.6). The patients were followed for 12 months; the final volume of solid residue was 0.1–2 mL (mean 1 mL) representing volume reduction by 80–99% (mean 92%). Therapeutic success (volume reduction > 50%) was achieved in all patients. Conclusion: US-PEIT of cervical cysts as an alternative to surgery can be used especially in elderly patients with increased surgical risk or in patients refusing surgery. In middle-aged and older adults, the possibility of a necrotic metastatic lymph node should always be considered. Therefore, a benign cytological examination and an unsuspecting ultrasonographic and CT finding are the basic conditions before performing the ethanol ablation.
