Ganglioneuroma
Learn about Ganglioneuroma, its reported features, relevant specialists, and questions to discuss at a medical consultation.
The sources compiled here do not cover: diagnosis, treatment, prevention, prognosis, prevalence. Ask the treating doctor about these.
What it is
From: Orphanet
Ganglioneuroma is a rare tumor of neuroepithelial tissue, a benign and well-differentiated tumor of neural crest origin, arising from the sympathetic nervous system and composed of ganglion cells and stromal Schwann cells. It can arise anywhere from the base of the skull to the pelvis, with the most frequent locations being the adrenal glands, retroperitoneum, posterior mediastinum and the pelvis, or, in rare cases, the central nervous system, heart, bones, intestine or other sites. It may be asymptomatic or present with various symptoms due to mass effect. Association with neurofibromatosis type I, multiple endocrine neoplasia type 2B and Turner syndrome was reported.
Reported clinical features and what the terms mean
The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.
The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.
- Ganglioneuroma · Obligate (100%)
- A benign neoplasm that usually arises from the sympathetic trunk in the mediastinum, representing a tumor of the sympathetic nerve fibers arising from neural crest cells.
- Abnormal mediastinum morphology · Frequent (79-30%)
- Any structural anomaly of the central compartment of the thoracic cavity.
- Abnormality of the adrenal glands · Frequent (79-30%)
- Abnormality of the adrenal glands, i.e., of the endocrine glands located at the top of the kindneys.
- Colorectal polyposis · Frequent (79-30%)
- Multiple abnormal growths that arise from the lining of the large intestine (colon or rectum) and protrude into the intestinal lumen.
- Multiple intestinal neurofibromatosis · Frequent (79-30%)
- Episodic abdominal pain · Occasional (29-5%)
- An intermittent form of abdominal pain.
- Hamartomatous polyposis · Occasional (29-5%)
- Polyp-like protrusions which are histologically hamartomas. These can occur throughout the gastrointestinal tract. Hamartomatous polyps are composed of the normal cellular elements of the gastrointestinal tract, but have a markedly distorted architecture.
- Hypertension · Occasional (29-5%)
- The presence of chronic increased pressure in the systemic arterial system.
- Neoplasm of the adrenal gland · Occasional (29-5%)
- A tumor (abnormal growth of tissue) of the adrenal gland.
- Functional intestinal obstruction · Occasional (29-5%)
- Abnormal bone structure · Very rare (<4-1%)
- Any anomaly in the composite material or the layered arrangement of the bony skeleton.
- Abnormal prostate morphology · Very rare (<4-1%)
- An abnormality of the prostate.
- Abnormality of the rectum · Very rare (<4-1%)
- An abnormaltiy of the rectum, the final segment of the large intestine that stores solid waste until it passes through the anus.
- Gastrointestinal hemorrhage · Very rare (<4-1%)
- Hemorrhage affecting the gastrointestinal tract.

When it may begin
From: Orphanet
Adolescent; Childhood; Infancy
Which doctor should you see?
The suggested department for discussing Ganglioneuroma is Oncology, with a oncologist and relevant organ specialist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.
Additional services that may be relevant, depending on the findings, include: Clinical Genetics; Relevant organ specialist / Surgical Oncology as indicated.
This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.
How to prepare for an assessment
Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.
Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.
- Has the exact tumour type been confirmed, and is staging relevant?
- What is the goal of each proposed treatment option?
- How will side effects, daily function and supportive care be addressed?
Treatment discussions and follow-up
The material gathered for this draft does not provide a complete condition-specific treatment pathway for Ganglioneuroma. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.
Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.
The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.
When to seek emergency help
Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
Oncology is not listed separately on The Doctor Index; the nearest speciality is medical oncology. Every profile shows the doctor’s registration and what has been checked.
