Ganglioneuroma
Ganglioneuroma (/ɡæŋˌɡliːoʊnʊˈroʊmə/; from Greek ganglion "knot" and neuroma "tumor") is a rare, benign neoplasm that originates from nerve ganglion cells and is most commonly found in the adrenal glands and posterior mediastinum.
Etymology
The term Ganglioneuroma is derived from the Greek words ganglion meaning "knot" and neuroma meaning "tumor". It refers to a tumor that arises from ganglion cells, which are nerve cells that are part of the autonomic nervous system.
Definition
A Ganglioneuroma is a type of neuroblastoma that has matured into a benign form. It is a noncancerous tumor that usually forms in the nerve tissue of the adrenal glands, but can also occur in nerve tissues along the spine, chest, abdomen, or pelvis.
Symptoms
Symptoms of Ganglioneuroma can vary greatly depending on the location of the tumor. Common symptoms may include abdominal pain or discomfort, unexplained weight loss, and hypertension. However, many Ganglioneuromas are asymptomatic and are discovered incidentally during imaging studies for unrelated conditions.
Diagnosis
Diagnosis of Ganglioneuroma typically involves imaging studies such as CT scans or MRI, and may be confirmed through a biopsy of the tumor.
Treatment
Treatment for Ganglioneuroma often involves surgical removal of the tumor. In some cases, if the tumor is not causing symptoms and is not growing, watchful waiting may be recommended.
