What Is A Parathyroid Tumor

Thyroid Nodules

A parathyroid tumor is a growth inside a parathyroid gland. The parathyroid glands are 4 small, pea-sized glands located in your neck near the thyroid gland. Theyre part of the endocrine system. This system controls hormones in your body. The parathyroid glands make parathyroid hormone. This regulates the levels of calcium and phosphorus in your blood. Parathyroid tumors may increase the levels of parathyroid hormones. This leads to more calcium in your blood. This is called hypercalcemia. Most parathyroid tumors are benign adenomas. Parathyroid cancers are very rare.

Summary Of Different Parathyroid Scans

Sestamibi scanning is the best way to find a parathyroid tumor. But as you know, it will only show about half of the parathyroid tumors and is frequently wrong when positive. There are several other tests used that can occasionally discover which parathyroid gland enlarged. Some tests simply use pictures of one form or another to find a BIG gland. These studies just look at parathyroid SIZE. Of course, there are other small things in your neck which can give false tests. Thus, CAT Scans, and MRI Scans should NOT be used to find a bad parathyroid gland. Let us repeat this: If your doctor orders an MRI scan on you to find a parathyroid tumor then get up and walk out.MRI and show less than 5% of ALL parathyroid glands. Therefore, if you have a CAT scan or MRI scan, you have a 95% chance of having a test that costs money, takes time, and won’t help a thing .

The following list describes briefly the different tests which may help a surgeon or endocrinologist find the diseased parathyroid gland which is over secreting parathyroid hormone.

How Is A Parathyroid Tumor Diagnosed

Should you take vitamin D if you have hyperparathyroidism? With care, vitamin D supplementation can safely be given to selected patients with asymptomatic primary hyperparathyroidism and is suggested before deciding on medical or surgical management. Monitoring serum calcium concentration and urinary calcium excretion is recommended while achieving vitamin D repletion.

Thereof, how many lobes does the parathyroid have?

Beside above, what is the location of parathyroid gland? Parathyroid glands are four small glands of the endocrine system which regulate the calcium in our bodies. Parathyroid glands are located in the neck behind the thyroid where they continuously monitor and regulate blood calcium levels.

Consequently, what are the 4 parathyroid glands?

The parathyroid glands are four tiny glands, located in the neck, that control the body’s calcium levels. Each gland is about the size of a grain of rice . The parathyroids produce a hormone called parathyroid hormone .

What is the normal size of parathyroid gland?

The average size of the normal parathyroid gland is approximately 4 mm to 6 mm in length, 2 mm to 4 mm in width and 1 mm to 2 mm in thickness, making detection by ultrasound difficult. However, enlargement of one or more of the parathyroid glands, due to an adenoma, for example, allows visualization by ultrasound.

Fine Needle Aspiration Of Thyroid Nodules

To find out if your thyroid nodule is benign or cancerous one usually begins with the Fine Needle Aspiration . Make sure that your doctor performs genetic testing and gives numbing medicine if needed for the thyroid nodule biopsy. Nodules in the thyroid that will likely be biopsied include:

  • size greater than 1.5cm according to ATA guidelines
  • suspicious ultrasound characteristics
  • patient with family history of thyroid cancer or history of radiation exposure
  • enlarging or painful nodules
  • enlarged lymph nodes near the thyroid or in the neck area

Treatment For A Parathyroid Tumor

Surgery is the main treatment for parathyroid tumors. The goal is to remove as much of it as possible. Before surgery, you may need treatment to control the amount of calcium in your blood.

In some cases, a parathyroid tumor doesnt need to be taken out. It may only need to be removed if your calcium level has reached a certain point or if you have severe symptoms.

If the tumor is cancer, you may need radiation therapy. This is done to kill the cancer cells or help keep them from growing and spreading. Chemotherapy may also be used to help do the same thing. In some situations, you may need medicines that lower calcium levels in your blood.

Can A Parathyroid Tumor Be Felt

Treatment with radiation therapy may increase the risk of developing a parathyroid adenoma. Possible signs of parathyroid cancer include weakness, feeling tired, and a lump in the neck. Most parathyroid cancer symptoms are caused by the hypercalcemia that develops.

Can you live without parathyroid? The most common cause of hypoparathyroidism is the loss of active parathyroid tissue following thyroid or parathyroid surgery. Even more rare is a defect present at birth , where a person is born without parathyroid glands. Occasionally, the specific cause of hypoparathyroidism cannot be determined.

Three Problematic Outcomes Of Parathyroidectomy

The frequencies of outcomes of parathyroidectomy differ in important ways between MEN-1 and other diagnoses . First because more than one gland is usually overactive in MEN-1, there is an increased rate of persistent HPT postoperatively, reflecting unexpected or hard to locate tumors. The incidence of postoperative persistent HPT can reach 4060% with inexperienced surgeons and is up to 25% even with experienced parathyroid surgeons . Second, because of the need for identification and removal of most parathyroid glands, the prevalence of postoperative hypoparathyroidism is relatively high at 025% . Third, the incidence of postoperative recurrent HPT is strikingly high in MEN-1 to the point of being a clue to undiagnosed MEN-1 . The time for 50% postoperative recurrence of HPT in MEN-1 has been 8 and 12 years after successful subtotal parathyroidectomy . High recurrence rate is also a feature with parathyroid autografts in MEN-1 . Recurrence probably comes from neoplastic parathyroid tissue remaining postoperatively or from mutational genesis of new neoplastic parathyroid clone . These three problematic surgical outcomes, relatively specific to MEN-1, have led to modified approaches to parathyroid surgery in MEN-1 .

Can A Parathyroid Tumor Be Mistaken For A Thyroid Nodule

Thyroid Nodule

Primary hyperparathyroidism occurs as a result of isolated parathyroid adenoma in 80% to 85% of all cases. As neck ultrasonography is often used to make the differential diagnosis, parathyroid adenoma is sometimes mistaken for a thyroid nodule, resulting in the wrongful use of fine needle aspiration cytology .

Do parathyroid levels fluctuate? If I take blood from a normal person who does not have parathyroid disease and test it for parathyroid hormone levels, those PTH levels will not fluctuate much at all. They dump parathyroid hormone out into the bloodstream at random intervals.

Four Types Of Standard Treatment Are Used


Surgery is the most common treatment for parathyroid cancer that is in the parathyroid glands or has spread to other parts of the body. Because parathyroid cancer grows very slowly, cancer that has spread to other parts of the body may be removed by surgery in order to cure the patient or control the effects of the disease for a long time. Before surgery, treatment is given to control hypercalcemia.

The following surgical procedures may be used:

  • En bloc resection: Surgery to remove the entire parathyroid gland and the capsule around it. Sometimes lymph nodes, half of the thyroid gland on the same side of the body as the cancer, and muscles, tissues, and a nerve in the neck are also removed.
  • Tumor debulking: Surgery to remove as much of the tumor as possible. Sometimes, not all of the tumor can be removed.
  • Metastasectomy: Surgery to remove any cancer that has spread to distant organs such as the lung.

Surgery for parathyroid cancer sometimes damages nerves of the vocal cords. There are treatments to help with speech problems caused by this nerve damage.

Radiation therapy


Supportive care

Supportive care is given to lessen the problems caused by the disease or its treatment. Supportive care for hypercalcemia caused by parathyroid cancer may include the following:

How Are Parathyroid Adenomas Distinguished Morphologically From Parathyroid Hyperplasia Or Parathyroid Carcinoma

Parathyroid adenomas present as nodular enlargement of one parathyroid gland, whereas the size of the other three glands remains normal. Occasionally a rim of compressed normal parathyroid may be seen at one pole of the adenoma or carcinoma. In contrast, parathyroid hyperplasia leads to an enlargement of all four parathyroid glands. Parathyroid carcinomas may be indistinguishable from parathyroid adenomas, and the only definitive sign that a tumor is malignant is the presence of metastases. Histologic examination of parathyroids is of limited value: both the adenomas and carcinomas and the hyperplastic parathyroids are composed of relatively uniform water-clear or oxyphil cells. These cells squeeze out the fat cells normally found in the parathyroid glands.

Types Of Scans To Locate An Abnormal Parathyroid Gland

Once the patient is diagnosed with hyperparathyroidism , we must take every step to identify the location of abnormal gland or glands. As you will have read by now, the patient may have one abnormal gland or a parathyroid adenoma , they may have 2 or more adenomas , or all 4 glands could be abnormal or parathyroid hyperplasia in 5% of people suffering from hyperparathyroidism.

D Parathyroid Ct Scan

The 4D Parathyroid CT scan is the newest imaging study to locate an abnormal parathyroid. It is the most accurate of the localization studies. It works based on the fact that abnormal parathyroid glands have more blood flowing through them then normal glands, and also the blood passes through the abnormal parathyroid gland at a different rate than the thyroid gland and lymph nodes. This difference is visible when the CT scan is done at different times after the contrast dye is injected into the bloodstream. This type of scan shows the anatomy in great detail which not only identifies the abnormal parathyroid gland but also in relation to the tissue around it, including the thyroid gland, blood vessels, breathing tube, and esophagus. It will show if the abnormal parathyroid is close to the area of the voice box nerve, even though the nerve itself is not visible, the anatomic path is well known to your surgeon. It can also show a gland that is not in the normal position , anywhere from the upper neck and all the way down into the chest.

PROS 1. Very accurate. 2. Can show parathyroid glands anywhere in the neck and chest even if they are hiding behind the voice box, breathing tube, chest or collar bones. 3. More anatomic detail than a sestamibi scan or a SPECT scan. 4. More accurate even when the tumor is small and PTH levels are only slightly elevated.

CONS 1. Exposure to radiation at a higher dose then Sestamibi or SPECT scans.

Can Parathyroid Cause Trouble Swallowing

Many patients with parathyroid disease have the perception of abnormal swallowing function. In these patients with symptoms of dysphagia, parathyroid surgery leads to significant improvements in many aspects of swallowing-related quality of life measured by the SWAL-QOL instrument.

Does hyperparathyroidism cause fatigue? Depression, Fatigue, Anger Management, and Hyperparathyroidism. High blood calcium due to hyperparathyroidism is well known to cause psychiatric problems. Fatigue is the most common symptom of hyperparathyroidism.

Parathyroid Glands Can Be Hard To Find Sestamibi Scans Ultrasound And All Other Types Of Scans Are Discussed Remember You Care Most About Your Surgeon’s Skills Because Scans Are Wrong More Than They Are Right Scans Are Wrong More Than They Are Right

If you have hyperparathyroidism , you have about a 70% chance of having one bad parathyroid gland . However, 30% of you will have more than one bad parathyroid gland . This is why you want your surgeon to examine all four–there is no way to know if a second tumor exists without looking at all four of them.

Since hyperparathyroidism can only be treated with surgery, then it should be obvious to you that the goal of the operation is to remove ALL of the BAD parathyroid glands. It should seem obvious as well, that if you have two bad parathyroid glands and your surgeon removes only one, then you will not be cured. If we can get you to understand this simple fact, then we are half way there! Your parathyroid surgeon must remove all the bad parathyroid glands or the surgery will be unsuccessful and the patient will not feel better or gain any benefit from the operation. Removing one tumor and leaving a second tumor behind does little or nothing for the patient. There is no benefit.

Great Idea!! Let’s get a scan or x-ray of some form to tell us how many parathyroid glands are bad, and where these bad parathyroid glands are located! .
