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.

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.

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.

Two rare cases of intraventricular arachnoid cyst locating in the posterior portion of the third ventricle are presented. A diagnosis was based on the radiological and operative findings and the microscopic features. Cyst wall fenestration by a direct approach resulted in good outcome. The orgin and the management of arachnoid cyst are discussed.
