Yes, paraganglioma can recur after surgery. However, this risk is generally low. The risk of recurrence after treatment is less than 10%. The recurrence rate of the disease after surgery for bladder paragangliomas is 2.6%. Even with complete resection, recurrence can occur in 8-20% of cases. Additionally, the risk of metastasis is between 28-50%. Therefore, long-term follow-up is required after surgery. The European Endocrinology Society recommends at least 10 years of follow-up for patients who undergo surgical treatment. Lifelong follow-up should be considered for high-risk patients and those with genetic predisposition. Since most paragangliomas grow slowly, annual check-ups are deemed sufficient. Paragangliomas can occur at any age. However, they are most commonly diagnosed in adults aged 30-50. Some studies report that the most common period is between 40-60 years. The disease is particularly seen in the 4th and 5th decades. One study found the average age of patients to be 48. The age distribution varies between 26-74. In young patients, the likelihood of paraganglioma due to hereditary reasons is higher. Therefore, individuals diagnosed at a young age should definitely undergo genetic testing. There is no guaranteed method of prevention. Because the exact cause of the disease is not known. However, since genetic factors play an important role, some preventive steps can be taken. For individuals with a family history, genetic counseling and regular screenings can help with early diagnosis. Genetic tests can be performed to understand whether the disease is common in the family and to identify individuals at risk. Maintaining a healthy lifestyle can help reduce risk. A balanced diet, regular exercise, and stress management support your overall health.

What is the Recovery Process After Surgery Like?
The recovery process is generally quick and smooth. At the end of the surgery, a tube called a drain is placed to remove blood accumulation from the field. This drain is kept for 1-2 days after surgery. After the drain is removed, there is no need to stay in the hospital.
Pain is usually mild. Using painkillers for the first few days will be sufficient to manage the pain. Nowadays, stitches are mostly made of self-dissolving types, so there is no need for stitch removal.
Dressing changes are completed in the week after surgery, and you can return home. You can also take a shower during this period. In some patients, discharge may occur on the third day. It is important to attend your follow-up appointments regularly.

Paraganglioma is a rare type of tumor that develops from clusters of nerve cells located in various parts of your body. Approximately 30-50% of these tumors are associated with hereditary syndromes. Paragangliomas are usually diagnosed between the ages of 30 and 50 and are mostly benign. In fact, the symptoms of paraganglioma vary depending on where the tumor is located and whether it produces hormones. What is paraganglioma, what are its symptoms, what are the diagnostic methods, and what are the treatment options including paraganglioma surgery? You can find all the details in this article.
What is Paraganglioma?
Tumors originating from paraganglia, which are specialized cell communities of your autonomic nervous system, are called paragangliomas. These cell clusters are located near sympathetic ganglia and plexuses throughout the body. The paraganglionic system includes chemoreceptors such as adrenal medulla, carotid and aortic bodies, vagal bodies, and cell groups associated with ganglia in various regions.
Paragangliomas are neuroendocrine tumors. These tumors originate from cells that can secrete hormones or hormone-like substances in response to nerve signals. They particularly release hormones known as catecholamines into the bloodstream.
Tumors originating from chromaffin cells in the inner part of the adrenal gland are called pheochromocytomas. Tumors that develop from paraganglia located outside the adrenal gland are referred to as paragangliomas. Pheochromocytomas constitute 80-85% of chromaffin cell-derived tumors, while paragangliomas make up 15-20%.
Types of Paraganglioma
Paragangliomas are divided into two main types: sympathetic and parasympathetic paragangliomas. This distinction is made based on the part of the nervous system from which the tumors originate.
Sympathetic paragangliomas are localized in the thorax, abdomen, and pelvis. These tumors secrete catecholamines. Due to catecholamine secretion, they can lead to symptoms such as high blood pressure and rapid heartbeat. Sympathetic paragangliomas have a higher risk of malignancy compared to pheochromocytomas.
Parasympathetic paragangliomas are localized in the head and neck. Most of these tumors do not produce hormones. The risk of malignancy for parasympathetic paragangliomas is less than 10%. In the past, these tumors have been referred to by many different names such as glomus tumor, chemodectoma, nonchromaffin paraganglioma, and carotid body tumor.
Differences Between Sympathetic and Parasympathetic Paragangliomas
There are significant differences between the two types of paragangliomas. The first is the difference in location. Sympathetic types develop in the chest, abdomen, and pelvis, while parasympathetic types are predominantly seen in the head and neck region.
The second important difference is hormone production. Sympathetic paragangliomas are functional and secrete catecholamines. Parasympathetic paragangliomas are generally non-functional and do not secrete hormones.
There are also differences in malignancy potential. About 10% of paragangliomas are malignant. However, sympathetic paragangliomas carry a higher risk of metastasis. Approximately 20-42% of paragangliomas metastasize, while only 2-10% of adrenal pheochromocytomas metastasize.
According to current medical understanding, paragangliomas are no longer classified as benign or malignant at the time of diagnosis. Instead, all paragangliomas are considered to have metastatic potential. Therefore, the characteristics of the disease at the time of diagnosis cannot clearly predict metastatic behavior. Thus, all paraganglioma patients require long-term follow-up.
What are the Symptoms of Paraganglioma?
Symptoms vary depending on the location of the tumor and whether it produces hormones. Some paragangliomas may not show any symptoms and may be discovered incidentally during routine check-ups. This is especially true for types that do not secrete hormones.
Commonly Seen Symptoms
Many paragangliomas in the head and neck do not produce hormones and appear as slow-growing, painless masses. They may not show symptoms in the early stages, leading to delays in diagnosis.
A painless swelling in the neck is the most common finding. The mass is usually palpable on the side of the neck and does not move up and down. It may grow over time and lead to cosmetic deformity.
The vascular structure of the tumor, its location, and its effects on surrounding structures determine the symptoms. Pulsatile masses, pain, and headaches may occur. Tumor-related anemia is rarely seen.
Symptoms of Hormone-Producing Paraganglioma
Paragangliomas originating from the sympathetic nervous system are more likely to produce hormones such as norepinephrine or dopamine. When functional, they cause symptoms associated with excessive catecholamines.
The classic triad includes hypertension accompanied by palpitations, headaches, and sweating. However, the classic triad is not observed in most patients. Headaches can vary in severity and duration and are seen in 90% of symptomatic cases.
High blood pressure, rapid heartbeat, sweating, and tremor episodes may occur. Pallor, anxiety attacks, nausea, and weight loss are among other symptoms. Attacks can last from a few minutes to several hours and usually start suddenly.
Paroxysmal hypertension is observed in approximately 50% of cases. Nevertheless, 5-15% of cases are normotensive. Generalized sweating is seen in 60-70% of symptomatic cases.
Tremors, facial pallor, shortness of breath, generalized weakness, and panic attack-like symptoms may accompany the picture. Disorders in carbohydrate metabolism may also develop due to increased catecholamines.
Symptoms of Paraganglioma in the Head and Neck Region
Middle ear tumors usually cause pulsatile tinnitus, changes in hearing, or a feeling of fullness in the ear. Pulsatile tinnitus occurs due to the transmission of vascular pulses in an overly vascularized tumor. Conductive hearing loss and ear pain are common.
Hoarseness occurs if the vagus nerve or recurrent laryngeal nerve is affected. Difficulty swallowing develops due to compression of the esophagus. Larger tumors or those close to nerves may lead to tongue weakness or other cranial nerve symptoms.
Headaches occur due to increased intracranial pressure or nerve involvement. Dizziness may develop due to vascular pressure and decreased blood flow. Weakness in the face or shoulder occurs due to pressure on surrounding nerves.
Warning Signs Requiring Emergency Medical Intervention
Some symptoms require immediate medical attention. Sudden severe headaches should be evaluated immediately. Difficulty breathing or swallowing is critical.
If neurological symptoms such as weakness or numbness occur, immediate medical assistance should be sought. Rapid growth of a neck mass is a warning sign that should be noted.
In rare cases, conditions such as pheochromocytoma crises may present with hypertension, hyperthermia, changes in mental status, and dysfunction of other organs. These situations require emergency intervention.
How is Paraganglioma Diagnosed?
The diagnostic process occurs through the evaluation of your symptoms and the combination of various testing methods. Your doctor will first take a detailed patient history and perform a physical examination. Then, laboratory tests and imaging methods are used to confirm the presence of paraganglioma.
Clinical Evaluation and Physical Examination
In the initial evaluation phase, your doctor collects information about your symptoms, family history, and previous illnesses. If there is a mass in the neck, the characteristics of the mass are examined during the physical examination. Carotid body paragangliomas show immobility in the cephalocaudal-vertical plane, a finding known as the Fontaine sign.
The presence of a pulsatile mass is a typical finding for paraganglioma. Your doctor will assess the size, firmness, and adherence of the mass to surrounding tissues. A neurological examination is performed to determine if there is cranial nerve involvement. A preoperative vocal cord examination is recommended, especially to evaluate the movements of the vocal cords.
Blood and Urine Tests
Blood and urine tests are performed to measure hormone levels. These tests detect excess hormones produced by paraganglioma cells. The levels of catecholamines and their metabolites, metanephrines, are measured in the blood or urine.
A 24-hour urine collection is performed to examine fractional catecholamine and metanephrine values. Since the negative predictive value of plasma fractional metanephrines is high, if normal, the diagnosis of paraganglioma is ruled out. If the metanephrine level is elevated, pheochromocytoma is suspected, while an elevated normetanephrine level suggests a tumor may be present anywhere in the body.
A tumor marker called Chromogranin A can also be measured through blood tests. Additionally, measurements of urine dopamine, plasma metoxytyramine, neuropeptide Y, and vanillylmandelic acid can be performed. Medications that may affect test results should be evaluated in advance.
Imaging Methods
Various imaging techniques are used to determine the location and size of the tumor. In sporadic cases, computed tomography or magnetic resonance imaging is the first preferred method. The sensitivity of these methods is 98-100%, and their specificity is around 70%.
In CT imaging, paragangliomas appear as solid lesions with a density similar to muscle, usually homogeneous. In MRI imaging, they give isodense signals in T1-weighted sequences and hyperintense signals in T2-weighted sequences. Both methods show rapid contrast retention.
Functional imaging methods are preferred in cases of suspected metastatic disease or multiple tumors. Metaiodobenzylguanidine (MIBG) scintigraphy accumulates in paraganglioma tissue. The sensitivity of 123I-MIBG is between 83-100%, and its specificity is between 95-100%.
PET scans evaluate the metabolic activity of the tumor. Ga-68 DOTATATE PET is particularly sensitive, with a detection rate of 93%. This rate is higher than that of F-18 FDOPA PET (80%) and F-18 FDG PET (74%).
Ultrasound is used as the first-line diagnostic method for head and neck paragangliomas. Doppler ultrasound evaluates the vascular structure of the tumor. Due to being a vascular lesion, preoperative biopsy is usually not preferred.
Genetic Testing and Counseling
Paragangliomas are highly often caused by hereditary gene mutations. Therefore, genetic testing is strongly recommended regardless of your age or the location of the tumor. Genetic screening is recommended if there is a family history of paraganglioma or pheochromocytoma.
Genetic analysis should be performed in the presence of bilateral tumors, cases seen under the age of 45, and findings suggesting a genetic disease. Loss of SDHB staining indicates hereditary syndrome and the risk of aggressive behavior. Genetic counseling is guiding both in screening and in determining diagnosis and prognosis.
How is Paraganglioma Treated?
The treatment approach is determined based on the tumor’s location, size, hormone production, and metastasis status. The only curative treatment option for pheochromocytoma and paraganglioma is surgical resection. The surgery aims to eliminate both excessive hormone secretion and tumor growth.
Preoperative Preparation and Hormone Control
If you have hormone-producing paragangliomas, you must receive medication treatment before surgery. Preoperative medical treatment is critical in reducing the risk of hypertensive crises that may occur during surgery.
Initially, treatment begins with alpha blockers. After about a week, beta blockers are added to the treatment. This is the most accepted approach. The target heart rate is set at 60-80 beats per minute. An alpha blocker called phenoxybenzamine can be used up to 240 mg per day. If your blood pressure remains high, metirozine can be given up to 2.0 grams per day. Metirozine is a drug that blocks the enzyme involved in the first step of catecholamine production.
You will be admitted to the hospital at least one day before the surgery. Sufficient fluids are provided through intravenous saline. You should avoid excessive exercise, heavy lifting, and emotional stress.
Paraganglioma Surgery
In the treatment of malignant paragangliomas, the priority is the removal of the mass. Surgical excision aimed at completely removing the tumor is the only way to treat paragangliomas that have spread to adjacent lymph nodes or organs. Despite complete resection, recurrence occurs in 8-20% of cases, and metastasis develops in 28-50% of cases.
Paragangliomas are usually highly vascularized structures. Therefore, identifying the vessels supplying the tumor through angiography and performing embolization is very important for the safety of the surgery to be performed. Materials used in embolization include gelfoam, liquid silastic, and teflon particles.
Most abdominal masses can be removed using laparoscopic surgery. This method involves making a few small incisions in your skin and removing the tumor with special instruments. Standard open surgery may be required for larger tumors. For the first time in Turkey, paraganglioma surgery was successfully performed using robotic surgery through the transperitoneal route. The patient was discharged on the third day after surgery.
Major complications after surgery include low blood pressure and sudden drops in blood sugar. Patients should be closely monitored for 24-48 hours for this reason. The mortality rate in surgery is 2.4%.
Radiation Therapy
Radiation therapy can be applied in cases where the tumor cannot be completely removed or has metastasized. Radiation therapy is a good alternative in cases where glomus tumors cannot be safely removed or have spread into the skull.
Stereotactic radiation therapy is a successful option in the treatment of paraganglioma. The administered treatment dose is a median of 25 Gy in 5 fractions. While lesions remain stable in some patients, complete or partial responses are achieved in others.
Chemotherapy and Targeted Drug Therapies
Chemotherapy is used in metastatic paragangliomas. Agents such as cyclophosphamide, vincristine, and dacarbazine can be administered. CVD combination chemotherapy is effective in treatment. Tumor response is achieved in 55% of patients, and biochemical response is achieved in 72%. The response duration is a median of 20 months.
Targeted drugs focus on abnormalities in cancer cells. Sunitinib increases disease-free survival in metastatic patients. Belzutifan is an oral agent that inhibits HIF-2α and prevents tumor growth.
Thermal Ablation Therapy
Radiofrequency ablation uses electrical energy to heat tumor cells. Cryoablation uses cold gas to freeze tumor cells. These methods can be applied in paragangliomas that have spread to organs such as bones or the liver.
Frequently Asked Questions
Patients often have many questions about paraganglioma. These questions cover a wide range of topics from diagnosis to treatment. Below you can find answers to the most frequently asked questions.
Is Paraganglioma Cancerous?
Paragangliomas are mostly benign. 85-95% of cases are of benign character. This means that the majority of these tumors do not spread to other parts of the body. However, some paragangliomas can be malignant and metastasize.
The overall malignancy rate is low. Approximately 6-10% of cases are malignant. The risk of malignancy is less than 10% for paragangliomas in the head and neck region. However, sympathetic paragangliomas in the abdomen and chest have a higher risk of metastasis.
The only reliable criterion for determining malignancy is the presence of metastasis. In other words, if the tumor has spread to lymph nodes or distant organs such as the lungs or liver, it is considered malignant. Histological examination alone may not be sufficient to distinguish between benign and malignant.
Is Paraganglioma a Hereditary Disease?
Yes, paragangliomas often arise from hereditary gene mutations. Approximately 30-40% of cases are associated with hereditary genetic syndromes. In fact, some studies show that at least 40% of paragangliomas are linked to hereditary mutations.
Familial transmission is autosomal dominant. Therefore, there is a possibility of passing from an affected parent to a child. In familial cases, the disease can appear in multiple regions in 30-50% of cases. This condition is referred to as multicentric disease.
There are also sporadic cases that develop spontaneously without genetic predisposition. However, genetic testing is recommended for all patients regardless of age or tumor location. Especially in children, the likelihood of hereditary causes is higher.

Dressing changes are completed in the week after surgery, and you can return home. You can also take a shower during this period. In some patients, discharge may occur on the third day. It is important to attend your follow-up appointments regularly.
Yes, paraganglioma can recur after surgery. However, this risk is generally low. The risk of recurrence after treatment is less than 10%. The recurrence rate of the disease after surgery for bladder paragangliomas is 2.6%. Even with complete resection, recurrence can occur in 8-20% of cases. Additionally, the risk of metastasis is between 28-50%. Therefore, long-term follow-up is required after surgery. The European Endocrinology Society recommends at least 10 years of follow-up for patients who undergo surgical treatment. Lifelong follow-up should be considered for high-risk patients and those with genetic predisposition. Since most paragangliomas grow slowly, annual check-ups are deemed sufficient. Paragangliomas can occur at any age. However, they are most commonly diagnosed in adults aged 30-50. Some studies report that the most common period is between 40-60 years. The disease is particularly seen in the 4th and 5th decades. One study found the average age of patients to be 48. The age distribution varies between 26-74. In young patients, the likelihood of paraganglioma due to hereditary reasons is higher. Therefore, individuals diagnosed at a young age should definitely undergo genetic testing. There is no guaranteed method of prevention. Because the exact cause of the disease is not known. However, since genetic factors play an important role, some preventive steps can be taken. For individuals with a family history, genetic counseling and regular screenings can help with early diagnosis. Genetic tests can be performed to understand whether the disease is common in the family and to identify individuals at risk. Maintaining a healthy lifestyle can help reduce risk. A balanced diet, regular exercise, and stress management support your overall health.

In Summary: Paraganglioma
Although paraganglioma is mostly benign, it can lead to serious symptoms and requires careful management. Therefore, early diagnosis and appropriate treatment are vital. If you notice symptoms such as a neck mass, persistent headaches, or abnormal blood pressure changes, you should definitely consult your doctor.
Even if the surgery is successfully completed, regular follow-up is essential. Paraganglioma can recur even years later. Genetic counseling and regular check-ups make a significant difference, especially for individuals with a family history. Do not hesitate to take all necessary steps to protect your health.

What is the Recovery Process After Surgery Like?
The recovery process is generally quick and smooth. At the end of the surgery, a tube called a drain is placed to remove blood accumulation from the field. This drain is kept for 1-2 days after surgery. After the drain is removed, there is no need to stay in the hospital.
Pain is usually mild. Using painkillers for the first few days will be sufficient to manage the pain. Nowadays, stitches are mostly made of self-dissolving types, so there is no need for stitch removal.
Dressing changes are completed in the week after surgery, and you can return home. You can also take a shower during this period. In some patients, discharge may occur on the third day. It is important to attend your follow-up appointments regularly.
