Case ReportsCystic parathyroid adenoma: Primary hyperparathyroidism without 99mTc-MIBI uptake.
Cystic parathyroid adenoma is a rare disease (<0.01% of all cervical masses) that associates primary hyperparathyroidism in 9% of cases. Parathyroid scintigraphy is essential for its diagnosis with uncommon false negative results. ⋯ Functional cystic parathyroid adenomas are surgically treated. A case of a 64-year-old woman with diagnoses of hyperparathyroidism and a cystic parathyroid adenoma without uptake in scintigraphy is described.
