title: [Renal osteodystrophy as a cause of false positive result of whole body scintigraphy in a patient with differentiated thyroid cancer].
abstract: We demonstrated the case of coexistence of secondary hyperparathyroidism in the course of irreversible renal failure and differentiated thyroid carcinoma diagnosed at the time of parathyroidectomy. Changes in skeletal system caused by secondary hyperparathyroidism resulted in false positive result of whole body scintigraphy and required differentiation with bone metastases of thyroid cancer. Therefore, the diagnostic tests of thyroid gland are necessary before parathyroidectomy in patients with secondary hyperparathyroidism.
