Summary
Ectopic parathyroid adenomas can complicate hyperparathyroidism diagnosis. This case highlights a mediastinal adenoma causing hypercalcemia, successfully treated with surgery, but followed by hypocalcemia.
Area of Science:
- Endocrinology
- Surgical Oncology
Background:
- Primary hyperparathyroidism (PHP) presents diagnostic challenges, particularly with ectopic parathyroid adenomas.
- Accurate localization of these adenomas is crucial for effective management.
Observation:
- A patient presented with symptomatic hypercalcemia attributed to an ectopic parathyroid adenoma.
- Initial ultrasonography suggested a thyroid nodule, but advanced imaging revealed an anterior mediastinal mass.
Findings:
- Computed tomography and technetium-99m sestamibi scintigraphy accurately localized the ectopic parathyroid adenoma in the anterior mediastinum.
- Surgical resection via median sternotomy was successful in removing the adenoma.
- Postoperative prolonged symptomatic hypocalcemia occurred, potentially due to parathyroid gland suppression or hungry bone syndrome.
Implications:
- This case underscores the importance of comprehensive imaging in diagnosing ectopic parathyroid adenomas.
- Management requires careful consideration of potential postoperative complications like hypocalcemia.
- Histopathological confirmation remains essential for definitive diagnosis.

00:59The Parathyroid Glands
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:29Appendicitis-II: Diagnostic Studies and Management
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...
