A glioma is a type of brain tumor that starts in the brain. It is a "primary brain tumor." This is different than a brain tumor that has spread from another area of the body, which is called a metastasis. There are a number of different types of gliomas which are named based on the type of cells. Brain stem gliomas are more common in children than in adults. For some children, they grow rapidly and spread to other parts of the brain. Brain stem gliomas in children are also called diffuse intrinsic pontine glioma. For a brain stem glioma, you usually have treatment with radiotherapy and chemotherapy. Coping with glioma.

Mar 01, 2012 · In contrast with the pediatric population in which brainstem gliomas represent up to 20% of brain tumors and exhibit a rather homogeneous and unfavorable course, adult brainstem gliomas are rare (accounting for only 1%–2% of adult brain gliomas) and heterogeneous with varying radiological patterns and variable prognoses [4, 5]. In this review Cited by: 58. Aug 09, 2016 · Appearance and Presentation. In contrast to pediatric DIPG, which accounts for approximately 20% of pediatric primary brain neoplasms, adult brainstem glioma constitutes less than 2% of adult gliomas, with a slight male preponderance (3, 4).Median age at diagnosis is in the mid-30s, though brainstem gliomas can present in any decade of life.Cited by: 8.

Prior radiation to the brain is a risk factor for malignant gliomas. Some genetic disorders also increase the risk of development of these tumors in children but rarely in adults. Jun 21, 2016 · In patients with adult brainstem glioma, Salmaggi et al observed that an elevated Cho/NAA ratio, an elevated Cho/Crea ratio, and an abnormal Crea/NAA ratio caused by loss of NAA signal was predictive of brainstem glioma in 9 patients. These changes are similar to the MRS characteristics reported in supratentorial adult gliomas.Cited by: 5.

A glioma is a type of tumor that starts in the glial cells of the brain or the spine. Gliomas comprise about 30 percent of all brain tumors and central nervous system tumors, and 80 Specialty: Oncology. Mar 01, 2012 · The median survival of diffuse intrinsic low-grade gliomas in adults ranges between 4.9 and 7.3 years as noted by three recent retrospective European and U.S. studies focused on adult brainstem gliomas [4, 5, 11]. In rare cases, a more aggressive diffuse intrinsic form similar to children appears in adults (that is, corresponding to a malignant.
