Thyroid nodule with cytological outcome of indeterminate lesion with low risk of malignancy found to be parathyroid adenoma. A case report and minireview of literature.

Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder, typically caused by a single parathyroid adenoma. The diagnosis of PHPT is biochemical, and the localization of abnormal parathyroid glands is usually achieved through a combination of ultrasound and technetium-99m sestamibi (99mTc-MIBI) scans. In some cases, newer imaging modalities, such as positron emission tomography-computed tomography (PET-CT) with 18F-fluorocholine or 11C-methionine, are used as second-line methods.
