Parathyroid cysts are a very rare disease entity. Hormone activity is uncommon and they usually present without any clinical symptoms. The differential diagnosis of cystic neck masses should nevertheless include parathyroid cysts as surgical therapy can be very effective. We report the case of a 57-year-old patient presenting to our department with a hormone inactive parathyroid cyst. Final diagnosis was achieved eventually after histological examination of the resected specimen, which is the reason for evaluating the current data for preoperative management of this disease entity in this case report.
