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.

What size of pheochromocytoma is malignant?

The size of pheochromocytomas and the benign or malignant nature of the tumor are not greatly related. Usually, most are familial pheochromocytomas, which are most commonly bilateral, but they have a relatively high recurrence rate and are difficult to treat with fewer available treatment options. Once a pheochromocytoma is detected, it should be taken seriously and treated promptly. The presence of a tumor often indicates that it has developed to the mid and late stages, where it becomes relatively difficult to cure. Regardless of whether the tumor is large or small, it must be taken seriously and treated with care, otherwise, it may easily worsen and affect health.

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.

Pheochromocytoma blood pressure how much

For patients with pheochromocytoma, they often present with a hypermetabolic state, elevated blood pressure, even reaching above 200 mmHg, along with significant hypertension and hyperglycemia. Patients may experience headaches, dizziness, nausea, vomiting, profuse sweating, and even chest pain and labored breathing. When such symptoms occur, it is important to promptly take the patient to a local hospital for medical attention. Appropriate tests should be conducted to help confirm the diagnosis and determine the specific location of the pheochromocytoma. Treatment typically involves surgical intervention, but it is essential to manage blood pressure with appropriate antihypertensive drugs before, during, and after treatment.

What should I do if a pheochromocytoma ruptures?

When a pheochromocytoma ruptures, it is advised that the patient immediately goes to the emergency department of the hospital for relevant examinations to confirm the diagnosis and to immediately control the blood pressure to a relatively stable and safe level. After a comprehensive evaluation, the urology department will perform emergency surgical removal to save the patient's life. Spontaneous rupture and bleeding of adrenal pheochromocytoma is quite rare. The possible reasons might be long-term hypertension leading to poor vascular function, or rapid tumor growth with high capsule pressure causing vascular rupture. Additionally, intense exercise, excessive fatigue, and transient increases in blood pressure could also be triggering factors.
