Acoustic Neuroma Causes. There are two types of acoustic neuroma: a sporadic form and a form associated with a syndrome called neurofibromatosis type II (NF2). NF2 is an inherited disorder characterized by the growth of noncancerous tumors in the nervous system.
Benign astrocytoma: Benign tumors that occur in the brain or spinal cord. Symptoms and severity depends on the location and size of the tumors. More detailed information about the symptoms, causes, and treatments of Benign astrocytoma is available below.
Frequently asked questions The following is a list of questions that patients and caregivers often have about chordoma, its treatment, finding support and resources, and getting involved. Click or tap the box containing the question to view the answer.
Benign tumors are lumps or growths that may appear in many parts of body. In the case of benign lymphoma, the most usual site is the lymph nodes, but it can also develop in the skin, lungs, liver, eyes, gastrointestinal tract, soft tissues, or other sites.
Craniopharyngioma is a rare, usually suprasellar neoplasm, which may be cystic, that develops from nests of epithelium derived from Rathke's pouch. Rathke's pouch is an embryonic precursor of the anterior pituitary. Craniopharyngiomas are typically very slow growing tumors.
A single, small hemangioma usually requires no treatment. It will likely go away on its own. However, some cases require treatment, such as skin hemangiomas that develop lesions or sores. Treatment options include: Corticosteroid medication: Corticosteroids may be injected into the hemangioma to reduce its growth and to stop inflammation.
A meningioma is a tumor that forms on membranes that cover the brain and spinal cord just inside the skull. Specifically, the tumor forms on the three layers of membranes that are called meninges. These tumors are often slow-growing. As many as 90% are benign (not cancerous).
World Health Organization (WHO) Updates Official Classification of Tumors of the Central Nervous System. On May 9, 2016, the World Health Organization (WHO) published an official reclassification of Tumor Types of the Central Nervous System, which has moved the greater neuro-oncology field toward a more precise and accurate system of brain tumor classification.
Although benign tumors will not metastasize or locally invade tissues, some types may still produce negative health effects. The growth of benign tumors produces a "mass effect" that can compress tissues and may cause nerve damage, reduction of blood to an area of the body , tissue death and organ damage.
