Parathyroid adenoma causing spontaneous cervical hematoma: a case report

A case of parathyroid adenoma causing a spontaneous cervical hematoma is reported. A 55-year-old woman presented with painful swallowing, dysphagia, and dyspnea. Primary hyperparathyroidism and a parathyroid. tumor on the left side of the neck had been found 2 years earlier. Fiberoptic laryngoscopy and computed tomography (CT) showed a narrowing of the airway as a result of a retropharyngeal hematoma, and tracheostomy was carried out. Parathyroidectomy was performed 5 months after the absorption of the hematoma, with no complications. A pathological diagnosis revealed a parathyroid adenoma with hemosiderin deposition and fibrosis. Serum calcium and intact parathormone levels normalized post-operatively. Although a spontaneous cervical hematoma resulting from parathyroid tumors rarely occurs, it may lead to an airway compromise. Physicians should be aware of this if such tumors are managed conservatively without surgery.
