Abstract
Hemorrhage from the parathyroid tissue is a relatively rare phenomenon. We herein report our experience with a 43-year-old woman who experienced hemorrhage from parathyroid adenoma that was initially thought to be a neck abscess. Pain and swelling developed in the anterior region of neck, which was exacerbated over time, and on the 11th day after visiting our hospital for treatment, the patient experienced fever and dyspnea. A hematological examination revealed a high inflammatory response；based on the course of the disease and the imaging findings,the possibility of a neck abscess could not be ruled out, and we performed emergency operative treatment. The intraoperative findings revealed a tumoral lesion with a clear coating on the dorsal side of the thyroid；the inside of the tumor was filled with dark reddish-brown effusion. Based on histological findings, we diagnosed intratumoral hemorrhage of parathyroid adenoma. The postoperative course was favorable, and the patient was discharged on postoperative day 10. Hemorrhage from the parathyroid tissue is an important condition that should be differentiated when patients show swelling of the neck.
