Multiple parathyroid adenomas with variable ultrasonography and computed tomography findings in a patient with chronic kidney disease: A case report

Tertiary hyperparathyroidism is defined as a state of excessive secretion of parathyroid hormone after long-standing secondary hyperparathyroidism, which typically occurs in patients with chronic kidney disease. Tertiary hyperparathyroidism is typically characterized by marked parathyroid hyperplasia or parathyroid adenomas. Here we present a case of multiple parathyroid adenomas in a 23-year-old woman with tertiary hyperparathyroidism due to chronic kidney disease and describe the ultrasonography and computed tomography findings. To our knowledge, this is the first case of four parathyroid adenomas showing variable radiological features in a patient with tertiary hyperparathyroidism.
