Pheochromocytoma is a tumor of the adrenal glands. The tumor makes hormones called epinephrine and norepinephrine. This leads to an excess of the hormones in the body. These hormones help manage heart rate, blood pressure, and other tasks. Too much of these hormones in the body causes problems. Pheochromocytoma is rare and occurs most often in adults between ages 20 and 50. But about 10% of cases are in children. A child may have more than one tumor.
The tumor can be caused by both genes and environmental factors. About a quarter of the cases are part of a hereditary disease, such as:
Von Hippel-Lindau disease
Multiple endocrine neoplasia (MEN) syndromes
A child is at higher risk for pheochromocytoma if they have any of these:
The most common symptom is high blood pressure, which can be very high. The high blood pressure can cause:
Fast heart rate
Other symptoms can occur a bit differently in each child. They may include:
Poor weight gain despite a good appetite
Belly (abdominal) pain or bloating
The symptoms of pheochromocytoma can be like other health conditions. Make sure your child sees their healthcare provider for a diagnosis.
The healthcare provider will ask about your child’s symptoms and health history. They may also ask about your family’s health history. Your child will have a physical exam. Your child may also have tests, such as:
Blood tests and urine tests. These tests measure hormone levels.
MRI. This test uses large magnets and a computer to make detailed images of tissues in the body without the use of X-rays.
CT scan. This test uses a series of X-rays and a computer to make detailed images of the body. A CT scan can show bones, muscles, fat, and organs. CT scans are more detailed than regular X-rays.
Radioisotope scan. This test uses radioactive substances to create an image of the adrenal gland.
Genetic testing. This is specialized blood testing that looks for genetic diseases as a possible cause of the tumor.
Treatment is done by removing the tumor or tumors with surgery. Before surgery, your child’s healthcare provider may prescribe medicine to lower the high blood pressure. Most people are cured with surgery. But in some people, the tumor can grow back.
Complications can include heart damage or stroke caused by high blood pressure.
Ongoing medical care may be needed to check for growth of a new tumor. Family members may also want to consider genetic testing to see who else may be at risk for pheochromocytoma.
Get medical care for your child right away if they have episodes that include a headache, fast heart rate, and sweating. If your child has high blood pressure or other symptoms of pheochromocytoma, talk with their healthcare provider.

Before your visit, write down questions you want answered.
At the visit, write down the name of a new diagnosis and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
Ask if your child’s condition can be treated in other ways.
