[Sonographic diagnosis of enlarged parathyroid glands in hyperparathyroidism (author's transl)]

Fifty-nine patients suspected clinically of having primary or tertiary hyperparathyroidism have been examined since 1978 in order to localize enlarged parathyroid glands. With glands larger than 5 mm. this proved successful in about 90% of those situated in the neck. The sonographic features of enlarged parathyroid glands are poor echoes, smooth margins and the typical position on the medial and posterior surface of the thyroid gland. A requirement for diagnostic success is the use of modern compound apparatus with digital convertors and focussed high resolution probes.
