Ectopic mediastinal parathyroid is a common cause of recurrent and persistent hyperparathyroidism. Patients with recurrent and persistent hyperparathyroidism have elevated parathyroid hormone, which results in bone, vascular, and soft tissue abnormalities. While CT and MRI can be used to investigate ectopic parathyroid tissue, nuclear medicine Technetium-99m Sestamibi scan is the preferred method of imaging with sensitivity of 80%-90% and specificity of nearly 90%. Once identified, ectopic mediastinal parathyroid is treated with surgical resection though less invasive methods have gained popularity. We present a case of a 62-year-old female with recurrent secondary hyperparathyroidism that was localized to an ectopic mediastinal parathyroid gland.

Ectopic thyroid is a rare congenital anomaly that results from failure of decent from the foramen cecum to the primitive thyroid during the stage of embryogenesis. The specific prevalence ranges from 1 in 100,000-300,000 population. Development, genetics, and mutation play a role in the formation of ectopic thyroid.

Ectopic parathyroid glands result from abnormal migration during development. If not detected promptly, they can lead to persistent or recurrent primary hyperparathyroidism (pHPT). Inferior parathyroid glands are typically located in the anterior mediastinum, while superior parathyroid glands are often near the tracheoesophageal groove, both of which contribute to pHPT.

Introduction: The rarest form of renal ectopia, the thoracic kidney, has been documented in only about 200 cases worldwide. There are four recognized causes of congenital thoracic renal ectopia: renal ectopia with an intact diaphragm, diaphragmatic eventration, diaphragmatic hernia, and traumatic diaphragmatic rupture. This condition often presents as an incidental finding in asymptomatic patients.

Introduction: Ectopic parathyroid adenomas represent an important cause of refractory hyperparathyroidism. While most ectopic mediastinal parathyroid adenomas can be accessed through a transcervical approach, this is not always feasible, posing a significant challenge.
Case Presentation: We report the case of a 60-year-old female patient who presented with symptomatic hyperparathyroidism.
