title: Parathyroid adenoma causing a spontaneous cervical and mediastinal massive hematoma.
abstract: Cervical and mediastinal hemorrhaging caused by a spontaneous rupture of a parathyroid adenoma has been rarely reported. Herein, we report a case of a 52-year-old woman who experienced a sudden onset of cervical and mediastinal bleeding related to a parathyroid adenoma. The patient had a history of trauma to the left thorax with a fracture of two ribs. Ultrasonography and computer tomography revealed a nodule in the retrotracheal space and hematoma of the bilateral trachea and thorax. Laboratory examinations revealed significant hypercalcemia, hypophosphatemia, and a high level of intact parathyroid hormone. Surgery was performed and a dark-red, soft tumor was found behind the trachea, which adhered to the surrounding tissues. The pathological diagnosis was a parathyroid adenoma with hemosiderin deposition and fibrosis.
