Ganglioneuroblastoma is a variant of neuroblastoma that is surrounded by ganglion cells. It can be difficult to diagnose. [1] Nodular ganglioneuroblastoma can be ...
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.
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.
In children aged 0–14 years, the most common brain tumors are pilocytic astrocytomas (17.5%), embryonal tumors (15.7%), and malignant gliomas (25.7%). [15] The overall incidence rate of brain tumors in children is 6.2 per 100,000. [9] The distribution and behavior of nervous system neoplasms differ significantly between adults and children.
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.
The typical symptoms involve a combination of pain, loss of nerve function, and/or a palpable (or radiographically apparent) mass affecting a peripheral nerve. The etiology and importance of the last two symptoms should be apparent.
Symptoms may include: Swelling in the extremities (arms or legs), also called peripheral edema; the swelling often is painless. Difficulty in moving the extremity that has the tumor, including a limp. Soreness localized to the area of the tumor or in the extremity. Neurological symptoms. [3] Pain or discomfort: numbness, burning, or "pins and ...
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.
