Three cases of cervical hematoma derived from the parathyroid gland

Abstract

We report three cases with idiopathic neck bleeding from a parathyroid mass without any episode of injury. In all cases, acute-onset neck swelling, cervicothoracic subcutaneous hemorrhage and laryngopharyngeal submucosal hemorrhage were observed, and CT and blood test findings suggested a deep neck hematoma derived from a parathyroid mass. Their symptoms improved with conservative treatment. In case 3, parathyroidectomy was performed electively due to persistent hypercalcemia and high intact-PTH. It is important to note that a parathyroid mass can cause deep cervical hematoma due to sudden hemorrhage without any trigger (e.g., trauma).
