Oligoastrocytoma

Common Name(s)

Oligoastrocytoma

Oligoastrocytoma is a brain tumor that forms when two types of cells in the brain, called oligodendrocytes and astrocytes, rapidly increase in number to form a mass.  These brain cells are known as glial cells, which normally protect and support nerve cells in the brain.  Because an oligoastrocytoma is made up of a combination of two cell types, it is known as a mixed glioma.   Oligoastrocytomas usually occur in a part of the brain called the cerebrum and are diagnosed in adults between the ages of 30 and 50.   The exact cause of this condition is unknown.

Cerebellar low-grade oligoastrocytoma presenting with subarachnoid haemorrhage.
 

Author(s): Gopalakrishnan Viswanathan, Suresh Nair, Kesavadas Chandrasekhar, Radhakrishnan Vishnupuri

Journal: Turk Neurosurg. 2012 ;22(3):382-5.

 

Subarachnoid haemorrhage (SAH) associated with intra-axial tumours is extremely uncommon and is usually seen in association with intratumoural bleed. Tumours located near the ventricle or subarachnoid spaces have a higher propensity for SAH compared to intraparenchymal lesions. Low-grade ...

Novel genomic alterations and mechanisms associated with tumor progression in oligodendroglioma and mixed oligoastrocytoma.
 

Author(s): David Blesa, Manuela Mollejo, Yolanda Ruano, Angel Rodríguez de Lope, Concepción Fiaño, Teresa Ribalta, Juan Fernando García, Yolanda Campos-Martín, Jose-Luis Hernández-Moneo, Juan Cruz Cigudosa, Bárbara Meléndez

Journal: J. Neuropathol. Exp. Neurol.. 2009 Mar;68(3):274-85.

 

Combined 1p/19q deletions are very prevalent in oligodendrogliomas (OGs) and, to a lesser extent, in oligoastrocytomas (OAs). These losses are associated with responsiveness to therapy. Using array-based comparative genomic hybridization, we screened for recurrent genomic alterations ...
