[Percutaneous transthyroidal instillation treatment of parathyroid adenoma with ethanol in primary hyperparathyroidism].

In an 81-year-old woman with primary hyperparathyroidism 2.5 ml of 95% ethanol were injected transthyroidally, under ultrasound control and local anesthesia, into a parathyroid adenoma, about 2.5 X 1.3 X 1.1 cm in size. Unilocular deposition of ethanol into the adenoma proved ineffective, but multilocular injection normalized serum calcium and parathormone concentrations. There were no complications. If the topography is favorable, this method can be an alternative to operation.
