We present a patient with a history of thyroid cancer, presumably following
radiochemotherapy of a childhood medulloblastoma, who developed a primary
hyperparathyroidism 10 years after long-term postsurgical hypoparathyroidism.
All established imaging modalities failed to detect the origin and only
selective neck sampling could identify the suspected parathyroid adenoma causing
hyperparathyroidism. This encourages the use of selective neck vein
catheterization, particularly in patients with only slightly elevated
parathyroid hormone-levels or suspected small ectopic adenoma.
