title: Parathyroid ultrasonography and fine-needle aspiration biopsy in the diagnosis of secondary hyperparathyroidism.
abstract: Parathyroid tumours were sonographically detected in 24 out of 72 uraemic patients with clinical and biochemical findings of secondary hyperparathyroidism. In 12 out of 24 cases ultrasonically guided fine-needle aspiration biopsy of the tumours was performed in order to obtain a cytological specimen. In the eight patients who subsequently had surgical exploration of the neck, diagnostic accuracy of both ultrasonography and biopsy combined was 87 per cent.
