OBJECTIVE
Oligodendroglial tumors rarely occur after radiation therapy. Here, we report a rare case of anaplastic oligodendroglioma arising after radiation therapy, in which genetic analysis was performed.
METHODS
A 41-year-old man who had received radiation therapy for a tumor of the suprasellar
Oligodendrogliomas are rare slow-growing asymptomatic glial tumours that usually present in patients in their fourth to sixth decades of life. Neurological symptoms that may present include nausea, headache, vomiting, diplopia, confusion, focal weakness, numbness and seizures. The treatment of
BACKGROUND
Oligodendrogliomas are usually located in the frontal, parietal and the temporal lobe, with the ones in the fourth ventricle quite rare. Hence we want to introduce a case about the rare disease.

Li-Fraumeni syndrome (LFS) is a clinically and genetically heterogeneous hereditary syndrome with predominantly oncological manifestations, which is associated with mutations in the TP53, MDM2, and CHEK2 genes. The most common variant is a TP53 mutation.

Background Although germ cell tumors and pineal cell tumors account for most of the histologic tumor subtypes, > 17 different tumors can arise in this location. We report a rare case of a low-grade oligodendroglioma that arose in the pineal region. Clinical Presentation A young woman complaining of
An 18-year-old female patient was hospitalized with headache and disturbance of consciousness. Magnetic resonance imaging (MRI) revealed a tumor in the left parieto-occipital lobe. The tumor was totally removed, and postoperative radiation therapy was administered locally at 50 Gy. Ten months later,
BACKGROUND
Recent advances that have been made in diagnostic imaging, surgical technique, chemotherapy, molecular biology, and prediction of therapeutic response could have potential impact on the optimal diagnosis and treatment of patients with brain tumors, especially those with
This study, an analysis of variable prognostic factors affecting the treatment outcome for patients with oligodendroglioma, included a retrospective analysis of the medical charts of patients diagnosed with oligodendroglioma treated at our institution between 1975 and 1997. The endpoints analyzed
Oligodendrogliomas occurring rarely in children are incompletely characterized. The purpose of this study was to identify prognostic factors affecting the local control and survival in the management of children with oligodendrogliomas. We retrospectively analyzed clinical data on 20 pediatric
This patient presented with a rare case of metachronous, multicentric gliomas first manifesting as headache and nausea in 1983 when he was an 8-year-old boy. Computed tomography revealed a cerebellar tumor and the tumor was subtotally resected. The histological diagnosis was pilocytic astrocytoma,
Oligodendrogliomas represent the third most common type of glioma, comprising 4%-15% of all gliomas and can be classified by degree of malignancy into grade II and grade III, according to WHO classification. Only 30% of oligodendroglial tumors have anaplastic characteristics. Anaplastic
Pediatric oligodendrogliomas are infrequently occurring brain tumors and frequently thought of as benign. The literature examining treatment and outcome in this select population is sparse. A retrospective analysis of pediatric oligodendrogliomas treated at MD Anderson Cancer Center between 1973 and

Glioblastoma multiforme (GBM), the most common primary malignant brain tumor in adults, is characterized by extensive heterogeneity in its clinicopathological presentation. A primary brain tumor with both astrocytic differentiation and neuronal immunophenotype features is rare. Here, we
Scalp metastases from anaplastic oligodendroglioma (AO) are extremely rare and are mostly involved in intracranial recurrence or widely metastatic disease. Here, we described an exceptional case of histopathologically proven scalp metastasis of AO 6 years after surgical resection and
