Spontaneous rupture of a parathyroid adenoma presenting as a massive cervical hemorrhage: report of a case.
We report an unusual case of spontaneous rupture of a parathyroid adenoma causing cervical hemorrhage. A 60-year-old woman presented to our hospital after the sudden development of extensive ecchymosis of her neck and upper anterior chest wall. Computed tomography (CT) scanning revealed a hematoma in the left retrotracheal space, and laboratory examinations revealed significant hypercalcemia, hypophosphatemia, and a high level of intact parathyroid hormone. Primary hyperparathyroidism was diagnosed, but it was not until the hematoma had subsided, 4 months after her initial presentation, that a parathyroid adenoma was revealed by CT. An operation was performed, and a parathyroid adenoma with hemosiderin deposition was histologically diagnosed. Although this phenomenon is unusual, all endocrine surgeons should be well aware of the possibility of its occurrence.
