In our group of 176 performed operations with diagnosis of primary hyperparathyreosis during the period of 1994-1999 present thyreopathy has been established peroperatively as well as postoperatively in altogether 47% of patients. Due to high percentage of coincidence of these diagnoses the condition of establishing indication for surgical therapy appears to be necessary not only on parathyroidal glands, but also determining the extent of resection on the thyroidal gland. In terms of preoperative screening, besides usual investigation of sonography and scintigraphy, we can recommend MRI test, which is highly positive for patients with thyreopathy, particularly in the area of nodular thyroid mass. The advantage of MRI investigation enables more precise localization of ectopic parathyroidal adenoma.
