What does a pheochromocytoma do?
Pheochromocytoma is a rare tumor of adrenal gland tissue. It results in the release of too much epinephrine and norepinephrine, hormones that control heart rate, metabolism, and blood pressure.
What is a pheochromocytoma and how does it cause the classic symptoms the patient presented with?
The classic symptoms of pheochromocytomas (or pheos) are those attributable to excess adrenaline production. Often these patients will have recurring episodes of sweating, headache, and a feeling of high anxiety.
What are the three symptoms associated with pheochromocytoma?
Symptoms associated with secreting pheochromocytomas/paragangliomas include high blood pressure (hypertension), headaches, excessive sweating and/or heart palpitations. In most patients, pheochromocytomas/paragangliomas occur randomly for unknown reasons (sporadically).
What is pheochromocytoma medical term?
Tumor that forms in the center of the adrenal gland (gland located above the kidney) that causes it to make too much adrenaline. Pheochromocytomas are usually benign (not cancer) but can cause high blood pressure, pounding headaches, heart palpitations, flushing of the face, nausea, and vomiting.
What is secreted in pheochromocytoma?
Most pheochromocytomas secrete norepinephrine predominantly, whereas secretions from the normal adrenal medulla are roughly 85\% epinephrine.
Why is pheochromocytoma known as 10\% tumor?
They are often called the “10\% tumor” because it was commonly thought that 10\% of pheochromocytomas are: Malignant – 10\% behave like cancer and can spread. Bilateral – 10\% are found in both adrenal glands. Pediatric – 10\% are found in children.
What is the ICD 10 code for pheochromocytoma?
C74. 10 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
What hormones are secreted by pheochromocytoma?
These cells release certain hormones, primarily adrenaline (epinephrine) and noradrenaline (norepinephrine), that help control many body functions, such as heart rate, blood pressure and blood sugar.
How do you rule out pheochromocytoma?
Because catecholamine relase varies throughout the day, the best method of diagnosing pheochromocytomas is using a 24-hour urine collection. This involves obtaining a special urine container, which has a small amount of preservative, from a medical laboratory and filling it with one entire day’s worth of urine.
What are 4 possible treatments for pheochromocytoma?
The primary treatment for a pheochromocytoma is surgery to remove the tumor….Cancer treatments
- MIBG .
- Peptide receptor radionuclide therapy (PRRT).
- Chemotherapy.
- Radiation therapy.
- Targeted cancer therapies.
Can pheochromocytoma cause vision problems?
Patients with pheochromocytoma present with myriad symptoms and signs, giving rise to the tumor’s title of “great masquerader.” In the visual system, hypertensive retinopathy, choroidopathy and optic neuropathy are the main complications.
Where can pheochromocytomas be found?
When pheochromocytomas are located outside the adrenal glands, they are called paragangliomas. (See Paraganglioma) Outside the adrenal glands, these tumors can be found anywhere along the sympathetic nervous chain.
How many adrenal glands does a pheochromocytoma affect?
You have two adrenal glands —one located at the top of each kidney. Usually, a pheochromocytoma develops in only one adrenal gland. But tumors can develop in both. If you have a pheochromocytoma, the tumor releases hormones that may cause high blood pressure, headache, sweating and symptoms of a panic attack.
How old do you have to be to have a pheochromocytoma?
Most pheochromocytomas are discovered in people between the ages of 20 and 50. But the tumor can develop at any age. Surgery to remove a pheochromocytoma usually returns blood pressure to normal. Signs and symptoms of pheochromocytomas often include:
When is genetic testing indicated in the workup of pheochromocytoma?
Genetic testing is sometimes recommended for patients with pheochromocytoma who: Are aged 40 to 50 years. Have a tumor in one adrenal gland. Do not have a personal or family history of an inherited syndrome.
