title: [Diagnosis of recurrent secondary hyperparathyroidism using double-phase 99m-Tc-MIBI gammagraphy after total parathyroidectomy with autotransplantation].
abstract: We present two cases of uremic patients with poor medical control of their secondary hyperparathyroidism. They had to undergo surgery to control symptoms. A total parathyroidectomy with autotransplant in the forearm muscles was performed. After a symptom-free period, both showed a recurrence of their hyperparathyroidism. A double phase 99mTc-MIBI scintigraphy was essential in order to correctly locate hypertrophic parathyroid gland. In one case there was a cervical recurrence and in the second patient hyperplasia in a forearm gland autotransplant was found. Both patients remained asymptomatic with medication during their follow up.
