Diagnosing Paraganglioma

Overview

Paraganglioma is a type of neuroendocrine tumor that forms near certain blood vessels and nerves outside of the adrenal glands. Paraganglioma forms from a specific type of nerve cell called chromaffin cells. The cells help regulate blood pressure.

To diagnose paraganglioma, several examinations, screening tests, and procedures may be performed such as:

• Physical exam: Your healthcare provider will perform a physical exam to look for physical signs of a medical problem. They will check for pain, swelling, or the presence of masses within your body.
• Lab tests: Lab tests may be ordered by your healthcare provider to check samples of your blood, urine, or body tissues. These tests can help diagnose Paraganglioma by measuring certain substances in your body.
• Imaging studies: Diagnostic imaging studies are commonly used to look inside your body for clues that can help diagnose or manage paraganglioma. The type of imaging study chosen depends on your symptoms and the part of the body being examined. Examples include X-rays, magnetic resonance imaging (MRI), and computed tomography (CT) scans.

To determine the type, severity, or stage of paraganglioma and identify factors or indicators related to it, additional examinations, tests, or procedures may be necessary. Some common ones include:

• Family history assessment: Your healthcare provider may ask about your family history to identify any genetic factors that could contribute to the development of paraganglioma.
• Plasma-free metanephrines test: This blood test measures the amount of metanephrines in your blood. Metanephrines are substances produced when the body breaks down adrenaline or noradrenaline.
• Staging tests: After a diagnosis is made, additional tests may be conducted to determine if cancer cells have spread to nearby areas or other parts of the body. These staging tests help assess the severity and extent of Paraganglioma.

It's important to note that each individual's situation is unique, and the specific examinations, tests, and procedures recommended may vary. Consult with a healthcare provider who can evaluate your specific case and provide personalized recommendations based on your symptoms and medical history.
