A Case of Large Oligodendroglioma in Child

Oligodendrolioma constitutes 3-12% of intracranial gliomas and is a slowly growing, benign tumor. Though uncommon in childhood and adolescenee, most tumors are idertified in the adult with peak at the age of 40 years. It has a predilection for frontal lobe and shows characteristic microscopic findings. Calcareous deposits arre demonstrated radiologically in 40-60%. The authors have experienced a case of large oligodendroglioma arising from the right parietal lobe in child and reviewed the literatures.

A Case of Pineal Tumor Treated by Irradiation Following Ventriculo-atrial Shunt

The diagnosis and treatment of pineal tumor has captivated the interest of neurosurgeons for decades. Reports indicated that the majority of these tumors were malignant and thereby couild not be surgically removed and decompressed without high mortality and morbidity. And the pineal tumor especially germinoma is one of the mosdt radiosensitive intracranial tumors. Therefore a regime of radiotherapy combined with ventricular shunting, to relieve hydrocephalus, was advocated. In addition, with development of C-T we make the diagnosis easily and assess the result of treatment. We report a pineal tumor which was treated completely by irradiation following ventriculo-atrial shunt.

A Case of Primary Rhabdomyosarcoma of the Frontotemporal Bone

Primary rhabdomyosarcoma of the frontal and temporal bone is very rare. Rhabdomyosarcoma is usually a relentless, progressive which results in death of patients in a relatively short time. The authors report a case of rhabdomyosarcoma arisen right frontotemporal bone and reviewed the literatures.

A Case of Tuberculoma of Right Cerebellar Hemisphere

Tuberculoma, once the most frequent cause of intracranial mass lesion, are now rare. Except in cases in which meningitis develops owing to extension to the subarachnoid space, the symptoms of them are those of an expanding cerebral or cerebellar mass. A 18 years old female was admitted to Chungnam National University Hospital complaining of headache and severe vomiting. Neurological examination showed severe papilledema, trunkal ataxia and mild ataxic gait. Chest P-A and skull X-rays showed non specific finding. Total removal of mass in right cerebellar hemisphere after exploration of posterior fossa was done and it was confirmed of tuberculoma histologically. Postoperative course was uneventful and discharged with good health.

Congenital Thoracic Ependymal Cyst

Congenital intradural intramedullary ependymal cysts of the spinal canal are very rare. The following case history is presented to emphasize the clinical features and to lead to a discussion of the origin of these cysts. We report our case with the brief review of the articles.
