Intra-operative ultrasound localisation of a parathyroid adenoma

In around 85% of cases of primary hyperparathyroidism, thecause is a solitary parathyroid adenoma. Pre-operative detectionand localisation of an adenoma is often achieved through thecombined use of ultrasonography and radiolabelled nucleotidescans of the neck. The use of intra-operative ultrasonography canfurther assist in localisation, helping to minimise the need forexcessive exploration of the neck.
