Percutaneous Irreversible Electroporation for Recurrent Thyroid Cancer--A Case Report

A 74-year-old man presented with a small locoregional, histopathologically proven, fluorodeoxyglucose positron emission tomography/computed tomography-avid recurrence of follicular thyroid carcinoma in the left subglottic space after extensive surgical resection, adjuvant radioactive iodine therapy, and external beam radiation therapy. Because all established focal therapies were contraindicated, percutaneous irreversible electroporation was performed without complications. Follow-up imaging at 7 months showed a small ablation scar without signs for residual vital tumor tissue. Irreversible electroporation may be a viable treatment option for selected cases of recurring head and neck tumors that are unsuitable for other local treatments.
