Pheochromocytoma is a tumor that occurs in the adrenal gland. The tumor secretes a large amount of catecholamines, causing an increase in blood pressure. Diagnostic tests for pheochromocytoma can include a CT scan and MRI of the adrenal glands to confirm the presence of any adrenal mass. Additionally, ultrasound can also be used as an auxiliary test to help confirm the diagnosis. It is also advisable to check the levels of catecholamines in the blood and urine to further confirm the presence of an adrenal pheochromocytoma.

Malignant symptoms of pheochromocytoma

For pheochromocytoma, if not treated adequately, it often leads to severe hypertensive crises in patients, characterized by extreme spikes in blood pressure accompanied by profuse sweating, palpitations, shortness of breath, chest pain, and numbness in the limbs. Excessively high blood pressure can easily trigger pathological changes in the heart, kidneys, liver, and brain tissues, possibly leading to hypertensive brain hemorrhage, and even endangering the patient's life. Therefore, if pheochromocytoma is not managed and treated properly, it often results in critical illness and might even endanger the patient's life. It is recommended that once diagnosed, hospitalization should be sought promptly, and surgical treatment should be considered if necessary.

Pheochromocytoma Test Items

For pheochromocytoma, the usual tests include routine blood tests, routine urine tests, and biochemical examinations. Specific tests mainly involve collecting blood and urine catecholamine metabolites to help diagnose the condition. Furthermore, further localization diagnostics are conducted on the patient via abdominal ultrasound, as well as CT or MRI scans, to determine the specific location of the pheochromocytoma growth. Further examinations are conducted in preparation for subsequent surgery, with treatment generally recommended to be surgical. During treatment, antihypertensive drugs are used in conjunction to control blood pressure and maintain stability of the condition.

Pheochromocytoma typical manifestations

For pheochromocytoma, the term usually refers to tumors arising from the chromaffin tissue of the neural crest. Clinically, the main typical symptoms include severe hypertension, along with nausea, vomiting, intense headache, and dizziness. Additionally, it may also cause the patient to be in a continuous high metabolic state, characterized by persistent hyperglycemia, nausea, vomiting, and excessive sweating. If not treated promptly and effectively, it may pose serious threats to the patient's heart, brain, and kidneys. In severe cases, it could even be life-threatening. Surgery is commonly recommended for treatment.

What medication is used for pheochromocytoma?

For patients with pheochromocytoma, it is advisable to choose antihypertensive drugs during medication. Clinically, there are many types of antihypertensive drugs used to treat pheochromocytoma patients, such as alpha-adrenergic receptor blockers, beta-adrenergic receptor blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, vasodilators, catecholamine synthesis inhibitors, etc. These drugs can achieve desirable therapeutic effects. Of course, the main treatment for pheochromocytoma is through surgical methods. Only by effectively removing the tumor through surgery can a satisfactory therapeutic effect be achieved, fundamentally leading to a complete cure. (Please use medication under the guidance of a doctor.)

How is pheochromocytoma treated?

Currently, for the treatment of pheochromocytoma, it is primarily important that once diagnosed with pheochromocytoma, one should promptly visit the local hospital to arrange surgical treatment as soon as possible. By surgically removing the pheochromocytoma, this prevents the excessive secretion of catecholamines, which can lead to a hypertensive crisis in patients. Therefore, clinically, after diagnosing and locating the pheochromocytoma, receiving surgical treatment can often achieve satisfactory therapeutic outcomes. Typically, appropriate preparations must be made before surgery. Generally, prior to the operation, it is crucial to actively administer medications such as alpha-adrenergic blockers, beta-adrenergic blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, vasodilators, and catecholamine synthesis inhibitors to effectively treat and stabilize blood pressure.
