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.

How is pheochromocytoma diagnosed?

For the diagnosis of pheochromocytoma, further examinations need to be completed first. These examinations mainly include qualitative tests and localization tests. The qualitative tests are primarily conducted through laboratory tests to measure the levels of catecholamine-related metabolites to further determine the presence of the tumor. Localization tests are performed using abdominal ultrasound, abdominal CT, and, if necessary, high-resolution abdominal CT to pinpoint the location of the tumor. Once the qualitative and localization diagnostics are performed, it can be confirmed whether a pheochromocytoma exists and its specific location. Depending on the situation, surgery can be used to remove the tumor, in conjunction with pharmacological treatment.

The manifestations of pheochromocytoma crisis

For patients with pheochromocytoma, during a crisis, it generally manifests as a sudden increase in the patient's blood pressure, which can rise to above 200-300 mmHg. Additionally, the patient experiences severe headaches and dizziness, severe nausea and vomiting. Some patients may experience significant discomfort and tachycardia, arrhythmias. Some patients also suffer from abdominal or chest pain, labored breathing, and difficulty breathing, and even blurred vision. In severe cases, the excessively high blood pressure can lead to hypertensive cerebral hemorrhage or other unexpected cardiovascular and cerebrovascular diseases. The patient’s vital signs are extremely unstable, often accompanied by multiple organ dysfunction or failure.

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.

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.
