[Preoperative localization of parathyroid adenomas: significance, indications and results]

Preoperative localizing technics of a parathyroid tumour. The authors present a limited experience about preoperative localizing technics of a parathyroid tumour. Oesophagography and selenomethionine 75 scintigraphy were not useful. Ultrasonography and computed tomography localised 50% of the tumours. Selective thyroïd venous catheterization and radioimmunoassay are correctly predictive in 87,5% of the studied cases. The interest, morbidity and results of these different technics are discussed.
