For the examination of pheochromocytoma, it is generally recommended to use qualitative or localization diagnostic methods. Qualitative examinations typically involve collecting metabolites of catecholamines from urine and blood to further facilitate a definitive diagnosis. Localization examinations are conducted through abdominal ultrasound, CT, or MRI to further identify the specific growth location of the pheochromocytoma. After a definitive diagnosis through qualitative and localization examinations, surgery is generally recommended to effectively remove the pheochromocytoma. Additionally, antihypertensive medication can be used to help control symptoms.

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.

How is pheochromocytoma diagnosed?

For patients with pheochromocytoma, comprehensive examinations are necessary for diagnosis. For instance, measuring catecholamines and their metabolites in blood or urine can help determine if there is a noticeable increase in catecholamine levels. Furthermore, adrenal CT scans can be used to assess the condition, where in many cases, significant occupying lesions can be detected through adrenal CT scans. In addition, other related tests also hold diagnostic value and significance, such as magnetic resonance imaging, ultrasound, and related nuclear scanning tests, which can assist in qualitative and locational diagnosis.

Pheochromocytoma clinical manifestations

Pheochromocytoma typically presents with severe hypertension, with blood pressure even reaching above 200/140 mmHg, accompanied by significant discomfort, such as profuse sweating, chest pain, obvious difficulty in breathing, chest tightness, shortness of breath, and other clinical manifestations. Moreover, if not treated timely and effectively, it can even lead to a hypertensive crisis. It also poses a severe threat to the patient’s heart, kidneys, liver, and brain tissues. Some patients might develop cerebrovascular diseases due to very high blood pressure, such as hypertensive cerebral hemorrhage, which can threaten the patient's life.

Is pheochromocytoma a cancer?

Pheochromocytoma is not a cancer. It is a special type of tumor tissue that usually originates from the neuroectodermal chromaffin tissue. It can secrete catecholamines. Based on the specific origins of the tumor cells, it can be divided into types such as parasympathetic, paraganglioma, sympathetic, and ganglioneuroma. Most often, it presents with long-term hypertension, which can cause damage to the heart, brain, and kidneys due to prolonged hypertension, or severe increases in blood pressure can lead to hypertensive brain hemorrhage, thereby endangering the patient's life. Early treatment is often necessary.
