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.

What department does pheochromocytoma see?

Pheochromocytomas generally require a visit to urology for treatment. Initially, they mostly present with symptoms of hypertension, leading many to first visit cardiology. After differential diagnoses have ruled out other causes and confirmed pheochromocytoma, patients must then seek treatment from urology. Pheochromocytomas are generally located in the adrenal glands, hence they require surgical removal by a urologist. It is crucial to strictly control blood pressure during surgery, as fluctuations can be severe and significantly impact the patient's physical and mental health. Therefore, if a pheochromocytoma is detected, it is critical to seek timely medical treatment for a relatively better prognosis.

What department should I go to for pheochromocytoma?

Pheochromocytoma generally requires consultation at the endocrinology or surgical department. Please ask a physician to assess the current situation. For further examination and diagnosis of pheochromocytoma, qualitative and locational diagnostics are necessary. Qualitative diagnostics typically involve blood tests where levels of catecholamine metabolites in the blood and urine are tested to assist in diagnosis; locational diagnostics involve using CT scans, MRI, and ultrasound to help determine the specific location of the tumor. Treatment for pheochromocytoma generally involves surgical removal of the tumor once it is found, combined with medication treatment, which often leads to satisfactory therapeutic outcomes.

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 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.

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.
