An intradural arachnoid cyst is a relatively rare condition. Idiopathic arachnoid cysts are rare lesions that are not associated with trauma or other inflammatory insults. This report describes one case of an idiopathic arachnoid cyst treated by posterior laminectomy and an excision of the mass with a brief review of the relevant literature.

Cerebral ependymal cysts are very rare. About 30 cases have been reported in the literature. They mimic arachnoid cysts clinically and on imaging studies but are different from arachnoid cysts in pathological findings. They are believed to arise by the sequestration of a small segment of the primitive ependymal lining into either the cortical mantle or the perimedullary mesh. They occupy the central white matter of the frontal or temporoparietal lobes. The authors describe a case of septate ependymal cyst involving left sylvian fissure. The clinicopathological features, treatment, and results of previously reported cases are reviewed, and the etiology and pathogenesis of these cysts are discussed.

Intracranial arachnoid cysts are uncommon congenital lesions of considerable interest and importance, the origins and exact nature of which remain uncertain. They account for about 1% of all intracranial space-occupying lesions4). Its predilection sites are in the sylvian fissure, the interhemispheral fissure, the cerebral convexity, the base of the brain, and over the midline of the cerebellum in the posterior fossa6)11). We are reporting a case of arachnoid cyst, developed in the left sylvian fissure in a ten years old male patient.

Multiple extradural arachnoid cysts of the spine are extremely uncommon in children with only a few cases reported. The authors report a case of multiple extradural spinal arachnoid cysts in children with a review of the relevant literature.

We report a case of suprasellar arachnoid cyst with hydrocephalus which was diagnosed incidentally. This 41-year-old housewife had sympoms of hydrocephalus and hypophyseal dysfunction. Despite of well-functioning ventriculoperitioneal shunt and communication of the cyst with the ventricular system, the size of the ventricular system was never been normalized. She deteriorated progressively and eventually died shortly after the seventh operation. Unusual hospital couse is presented with brief review of the related literatures.

Recently we experienced stereotaxic endoscopic biopsy and resection of intracranial tumors using the Brown-Robert-Wells system. Surgical exploration was undertaken under the local anesthesia:1 germinoma in pineal region, 1 arachnoid cyst in basal cistern. The method is described, and the its potential clinical applications is discussed.
