Paraganglioma is a rare type of tumor that arises from the paraganglia, which are clusters of neuroendocrine cells found throughout the body. These tumors can develop in various locations, including near the adrenal glands, neck, and spine. They are often slow-growing and can be benign or malignant. Symptoms of paraganglioma may include headaches, sweating, rapid heartbeat, and high blood pressure, depending on their location and whether they produce hormones. Diagnosis typically involves imaging studies and biopsy, while treatment options may include surgery, radiation therapy, or medication to manage symptoms.
