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.

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.

The authors report two races of Arachnoid cysts located at the septum Lucidum. The presenting signs are those of Intracranial hypertension with cephalalgia and disc edema of the retina. The diagnosis can only be made by CT scanner with a cyst having the same density as the ventricular cerebro spinal fluid, and located at the “septum lucidum” between the lateral ventricles-surgery by transcallosal approach is indicated when appears the intracranial hypertension syndrome.

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.

Since October 1993 to October 1995, 11 cases of arachnoid cysts in infant of 2 months -14 years old were operated on at the neurosurgical dep of Hanoi Saint-Paul hospital. Results: excellent and good results: 7/11. Relative: 4/11 No death was reported. The author presents an analysis of detailed clinical signs, anotomo - pathology for clinical diagnosis and surgical treatment, and the method of choice for the treatment. The diagnosis must be made early by CT scaning or Echography.

The anterior middle fossa is the most common location of benign intracranial arachnoid cysts. In the adult, headache, temporal bulging, and mild proptosis are the usual presenting complaints, although seizures and contralateral weakness have been described. Bitemporal hemianopsia associated with this lesion has not been noted previously. Herein we describe the patient with bitemporal hemianopsia associated with sylvian fissure arachnoid cyst. Cystoperitoneal shunt was beneficial. The etiology, histology, and suggested therapy of other patient with arachnooid cyst are also discussed.

OBJECTIVE: The endocrine dysfunction after the operation for suprasellar arachnoid cysts is not rare. The careful operation to prevent structures can prevent this complication, but it is not enough and effective to prevent it. Authors present technical surgical considerations to prevent this complication with a review of our suprasellar arachnoid cyst patients who had postoperative endocrine dysfunction. METHODS: From January 2002 to December 2009, eight patients who had suprasellar arachnoid cysts with visual impairment underwent surgery. The mean age was 57.1 years (range, 33-77). Preoperatively, their endocrine function was clinically normal, and laboratory hormonal levels were within normal ranges. Cyst fenestration was performed by craniotomy (n=6) or by a neuro-endoscopic procedure (n=2), and, simultaneously, along with a cyst wall biopsy. RESULTS: The surgery was uneventful in all eight patients, and there were no neurological morbidities. However, in four patients, endocrine dysfunction occurred postoperatively. We compared these four patients (group A) to the other 4 patients without endocrine dysfunction (group B) with intraoperative findings and with the histopathological findings of the cyst wall biopsy. The group A patients had more abundant vasculature on the cystic wall than the group B patients according to both the intraoperative findings and the histopathological findings. CONCLUSION: When performing a surgical cyst wall fenestration, surgeons should try to minimize the destruction of the cystic wall vasculature and not to make the fenestration at a site that contains many vascular striae.

Suprasellar cistern is uncommon location where the arachnoid cysts involve and only sporadic case reports are seen in the world literature. A case of suprasellar arachnoid cyst is reported, which mimicked such clinically common perisellar lesions as pituitary adenoma, empty sellar syndrome, dermoid cysts, etc., and could be differentiated from them preoperatively with C.T. scan and pneumoencephalography.
