They are typically slow-growing and non-cancerous, and can arise from various locations within the autonomic nervous system, including the adrenal gland, chest, abdomen, pelvis and neck.
They usually contain a mixture of mature nerve cells, supportive tissue and abnormal nerve cells. They are often well-defined and encapsulated, and do not typically invade surrounding tissues or metastasise. Ganglioneuromas may not cause symptoms in many cases, especially if they are small, but depending on their location and size they may lead to pain, compression of nearby organs, or hormonal imbalances if they affect the adrenal glands.
Treatment often involves surgical removal, especially if the tumour is causing symptoms or complications. Where complete removal is not possible, or if the tumour is asymptomatic, close monitoring with regular imaging may be recommended.
