Parathyroid Cyst: A Case Report of an Uncommon Diagnosis of a Cervical Mass

Parathyroid cysts (PCs) are uncommon entities in clinical practice. The lack of pathognomonic clinical presentation and radiological features of PCs makes preoperative diagnosis unlikely, therefore, most cases are diagnosed intraoperatively or postoperatively at the pathological analysis of the surgical specimen. Treatment of nonfunctional PCs remains controversial and includes fine-needle aspiration, injection of sclerosant, or surgical excision. However, surgical resection still the optimal treatment for functional and larger nonfunctional PCs. We report a case of a 60-year-old female presenting with asymptomatic left-sided cervical swelling diagnosed postoperatively as a nonfunctional PC.
