Any symptoms will depend upon the tumor's location and the nearby organs affected. [citation needed] For example, a tumor in the chest area may cause breathing difficulty, chest pain, and trachea compression. If the tumor is located lower in the abdomen, it may cause abdominal pain and bloating.
Ganglioneuroblastoma is a variant of neuroblastoma that is surrounded by ganglion cells. It can be difficult to diagnose. [1] Nodular ganglioneuroblastoma can be ...
A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.
Symptoms depend on primary tumor locations and metastases if present: [7] In the abdomen, a tumor may cause abdominal distension and constipation. A tumor in the chest may cause breathing problems. A tumor pressing on the spinal cord may cause weakness, thus an inability to stand, crawl, or walk.
A ganglioglioma (or gangliocytoma) is a rare, slow-growing primary central nervous system (CNS) tumor which most frequently occurs in the temporal lobes of children and young adults. [3] They are mixed cell tumors containing both neural ganglionic cells and neural glial cell components.
Ectomesenchymoma is a rare, fast-growing tumor of the nervous system or soft tissue that occurs mainly in children, although cases have been reported in patients up to age 60. [1] Ectomesenchymomas may form in the head and neck, abdomen, perineum, scrotum, or limbs. Also called malignant ectomesenchymoma.
Children are much more prone to exhibit these dysembryoplastic neuroepithelial tumours than adults. [1] The mean age of onset of seizures for children with DNTs is 8.1 years old. [1] Few other neurological deficits are associated with DNTs, so that earlier detection of the tumour before seizure symptoms are rare. [2]
Less than 50% of children survive more than 5 years, [1] while the majority of adults live to 7 years. [2] The reason the prognosis for such tumor is worst in children is due to the higher probability of the tumor spreading to the rest of the nervous system through the cerebrospinal fluid and growing again.
