Summary
Giant functional parathyroid cysts (PCs) are rare causes of primary hyperparathyroidism (PHPT). This case highlights a unique ultrasonographic pattern mimicking thyroid disease, emphasizing PCs in differential diagnoses for cystic neck masses.
Area of Science:
- Endocrinology
- Surgical Pathology
Background:
- Giant functional parathyroid cysts (PCs) are exceptionally rare endocrine tumors.
- They pose diagnostic challenges due to nonspecific symptoms and imaging findings.

00:59The Parathyroid Glands
4.2K
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...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
