Oligodendrogliomas are a type of glial cell tumor arising from oligodendrocytes, glial cells that form insulation around neurons, that helps them conduct electrical impulses. These uncommon, usually slow-growing, tumors occur most often in middle-aged patients.
The symptoms of oligodendrogliomas are similar to those of other gliomas, but seizures in particular are the most common presenting symptom.
Like other brain tumors, these tumors are diagnosed with radiological imaging. Ninety percent of these tumors show some degree of hardening or calcification.
Surgery is the most common initial treatment, but it is especially important in the treatment of oligodendrogliomas because the benefits of radiation on these masses is not clear. As always, more complete tumor resection is associated with better outcomes. Recently, the role of chemotherapy as a viable treatment for some oligodendrogliomas has been established.
