“…Oligodendrogliomas are relatively rare tumors of the brain and constitute 0.9‐4% of all brain tumors and 3‐12% of all gliomas . Although oligodendrogliomas commonly arise in the cerebral hemisphere, including the frontal and temporal lobes, primary intraventricular oligodendrogliomas (IVOs) have rarely been reported . However, primary IVOs that were previously reported may in fact be central neurocytomas because central neurocytomas appear quite similar to oligodendrogliomas on routine light microscopic examination …”

Primary intraventricular oligodendroglioma (IVO) is a rare form of clear cell neoplasm and diagnosis is challenging because other clear cell neoplasms such as central neurocytoma must be ruled out. We report a case of primary IVO in which Olig2 immunohistochemistry was useful for the diagnosis. A 33-year-old man was admitted to our hospital with severe headaches due to an intraventricular mass lesion and underwent total resection of the mass lesion. The histological diagnosis was oligodendroglioma because the tumor was negative for synaptophysin and positive for Olig2. IVO is rare and differential diagnoses must be considered. The correct pathologic diagnosis is essential for anticipating the prognosis and selecting adjuvant therapy. In this case, Olig2 was useful for the diagnosis of oligodendroglioma.

Interventricular low-grade oligodendroglioma with multiple parenchymal relapse

SummaryOligodendrogliomas can be found anywhere oligodendrocytes exist; however, they mostly occur in frontal lobes. Although intra-and extra central nervous system dissemination of anaplastic oligodendroglioma is a well-known property of this tumour, low-grade oligodendroglioma with intracranial relapse is a very uncommon finding. In this case report, a 37-year-old man with grade II oligodendroglioma relapsed after 18 months with multiple parenchymal masses is presented. BACKGROUND

Oligodendrogliomas are relatively rare tumors that arise from the oligodendrocyte or its precursors. The role of postoperative radiotherapy (RT) in these tumors still remains unclear. Data concerning a study on 77 histologically verified cases of oligodendrogliomas of the brain among a total number of 1884 cases of an intracranial glioma treated at the Hacettepe Medical Centre between 1964 and 1991 were reviewed and analyzed (6.5%). One patient died in the early postoperative period and 8 patients in pediatric age group with an aggressive from of the tumor died within 6 months of treatment. The results suggest that oligodendrogliomas which arise in childhood primarily in the intraventricular region should be considered potentially more malignant than other lesions of this type. Because of this, we believe that postoperative radiotherapy is necessary to prevent the recurrences.
