Parathyroid cyst should be evoked, and signs and symptoms of hyperparathyroidism actively searched for when facing any cystic tumor in the anterior neck or the upper mediastinum. The best investigation for a functional cyst defined by hyperparathyroidism is US and sestamibi scan in order to localize the functional gland before surgery. US-guided fine-needle puncture should not be recommended in this setting. In cases of non-functional cyst, US-guided fine-needle puncture with analysis of both thyroid hormones and PTH levels will determine the further management of the cyst.
