Intrathyroidal parathyroid adenoma, a rare cause of hyperparathyroidism treatment failure, was diagnosed using MIBI scintigraphy. Surgical removal led to normalized laboratory results, confirming the imaging modality
Area of Science:
- Endocrinology
- Surgical Pathology
- Nuclear Medicine
Background:
- Intrathyroidal parathyroid adenoma is a rare anomaly, occurring in 1.4-6% of cases.
- Ectopic parathyroid adenoma localization, especially intrathyroidal, can lead to therapeutic failure in hyperparathyroidism management.
Purpose of the Study:
- To report a case of intrathyroidal parathyroid adenoma.
- To highlight the diagnostic utility of MIBI scintigraphy in identifying ectopic parathyroid tissue.
Main Methods:
- Case presentation of a 51-year-old patient with neck pain and goiter.
- Diagnostic imaging using Technetium-99m sestamibi (MIBI) scintigraphy.
- Surgical intervention via left loboishmectomy and subsequent histopathological analysis.
Main Results:
- MIBI scintigraphy identified an ectopic focus consistent with parathyroid origin.
- Histopathology confirmed parathyroid adenoma coexisting with dystrophic thyroid parenchyma.
- Post-surgical normalization of laboratory work-up.
Conclusions:
- Intrathyroidal parathyroid adenoma, though uncommon, is a significant cause of treatment failure in hyperparathyroidism.
- MIBI scintigraphy is the gold standard for diagnosing parathyroid ectopy, including intrathyroidal locations.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
