Résumé
Anaplastic oligodendrogliomas (AOs) correspond to 23% of all oligodendrogliomas. They correspond to a tumor with malignant histological characteristics, focal or diffuse, associated with a worse prognosis. In the present case report, we describe the case of a 30-year-old female submitted to resection of a right parietal lesion whose histology showed to be an AO. She underwent complementary treatment with chemotherapy and radiotherapy according to the Roger Stupp protocol. Four years after the initial diagnosis, there was tumor recurrence within the superior sagittal sinus, with no evidence of recurrence elsewhere. In the literature, we have found no similar published case reinforcing the rarity of this condition.

A rare case of a young man with a diffusely calcified oligo astrocytoma in right parieto occipital region, which spread along the axonal fibres into right temporal lobe and to the left parietal lobe is presented. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated the extent of the lesion. The mass was partially resected.

Fifteen pediatric (age under 16) cases of oligodendroglioma (ODG) were surgically proven from January 1985 to April 1992 at the Division of Pediatric Neurosurgery, Seoul National University Children's Hospital. To observe the proportion of ODG's in primary intracranial tumors, the location of ODG's and the prognostic significance of the histological grading of ODG's in childhood, the 15 cases of pediatric ODG's were retrospectively analyzed. ODG's accounted for 5.6% of pediatric primary intracranial tumors operated on during the same period. Nine tumors were located in the cerebral hemisphere (3 cases each in the frontal, temporal and parietooccipital lobes), 1 in the thalamus, 2 in the pons-medulla, 2 in the cerebellum and 1 in the thoracolumbar spinal cord. Four tumors were anaplastic and an additional case showed positive cerebrospinal fluid (CSF) cytology for tumor cells. All the cases of anaplasia or positive CSF cytology had a poor outcome. All the seven cases of benign ODG's in cerebral hemispheres presented with seizures which were controlled with or without medication after tumor removal.
