Abstract
Spontaneous hemorrhage from a parathyroid adenoma is rare. It can cause cervical ecchymosis or massive hematoma with hypercalcemia. We have encountered a case of parathyroid adenoma presented with spontaneous hypocalcemic tetany and massive cervical hemorrhage.
A 58-year-old man was referred to the hospital after the sudden onset of cervical ecchymosis following digital numbness which had been treated with a diagnosis of hypocalcemic tetany at another hospital. There was previous history of urolithiasis. CT and T1-201, Tc-99m scintigraphy demonstrated a small tumor behind the left lobe of the thyroid. Although intact-PTH was normal at presentation, it increased when he was admitted to the hospital 4 days later. The tumor was surgically removed and a parathyroid adenoma with hemosiderin deposition was histologically diagnosed. The intact-PTH level was normalized after the operation.
