1. Pathophysiology

There are 4 parathyroid glands located on the thyroid. They produce the parathyroid hormone that regulates the level of calcium in the blood. Routine assays include PTH and serium calcium tests.

2. Diagnosis

Diagnosis most often occurs involuntarily: following a blood test, when assessing lithiasis in the urinary tract, among patients suffering from kidney failure, or in the context of more complex pathologies such as MEN (Multiple Endocrine Neoplasia). High PTH associated with high levels of serum calcium suggests HPT1

3. Imaging report

Clinical examination is not contributory. Two routine examinations Thyroid ultrasound MIBI scan For more complex forms, diagnosis can be complemented with cervical MRI or CT scan. In 80% of cases, consistent results between ultrasounds and scans confirm the adenoma diagnosis.

4. Treatment

Treatment is surgical. It relies on exploratory cervicotomy. 20% of cases of double adenoma are not revealed through imaging, which is why the 4 parathyroid glands are explored during surgery. Complications: potentially compressive cervical hematoma, as well as relapse in some very rare cases.
