Contrary to what is frequently stated in the literature, preoperative localization of parathyroid adenomas is important. Surgery limited to removal of the adenoma is associated with significantly less morbidity than when bilateral exploration is undertaken. In fact, a 2 to 12 fold decrease in post-operative hypocalcemia has been reported when the surgical exploration is unilateral. Pre-operative CT scans localized 10 of 13 surgically proven adenomas for an overall detection rate of 77%. Only one adenoma in our series had an average axial diameter of greater than 1 cm, the smallest measuring 5 mm X 3 mm. This paper outlines our CT technique and results and summarizes the pertinent recent surgical literature in reference to the importance of preoperative localization.
