The middle fossa is the most common location for arachnoid cysts, with approximately 47–55% of all arachnoid cysts occurring in this location. Imaging features of arachnoid cysts are very characteristic and, in general, the diagnosis can be made accurately on the basis of MRI alone. The most likely pathophysiological explanation for arachnoid cysts is a developmental anomaly in splitting of the meningeal membranes. Surgical treatment is recommended for infants with massive cysts and progressive macrocrania, patients with suprasellar arachnoid cysts and obstruction of CSF pathways, and unusual cases where substantial cyst growth occurs or specific neurological signs are present. Cysts may be treated surgically with craniotomy and open fenestration, endoscopic fenestration, or cystoperitoneal shunting. Traumatic tears in the cyst lining may result in subdural hygroma formation, which can lead to increased intracranial pressure.

Intradural Arachnoid Cysts

Abstract Background Primary intradural spinal arachnoid cysts are rare pathologies of uncertain etiology and variable presentation from no symptoms to myelopathy or radiculopathy according to cord or root compression. MRI with diffusion and contrast differentiates them from many pathologies. There is a lot of debate regarding when to treat and how to treat such rare pathologies. Objective We present a series of 10 primary intradural arachnoid cysts and evaluate outcome after surgery. Methods This retrospective study includes patients having primary intradural spinal arachnoid cysts operated in two tertiary care centers from October 2012 till October 2019. Symptomatic cysts were subjected to microsurgical resection or outer wall excision and inner wall marsupialization under neurophysiological monitoring. The Japanese Orthopedic Association Score was used for clinical evaluation while MRI with contrast and diffusion was used for radiological evaluation before and after surgery. Results This series included 10 patients, 4 males and 6 females, with mean age of 40 years. Pain was the most common presentation. The most common location was dorsal thoracic region. Total excision was achieved in 2 cases and marsupialization in 8 cases. All symptoms improved either completely or partially after surgery. No neurological deterioration or recurrence was reported during the follow-up period in this series. Conclusion Treatment of symptomatic primary intradural spinal arachnoid cysts should be microsurgical resection, when the cyst is adherent to the cord, microscopic fenestration can be safe and effective.

Normal Relationship

Disharmony in the growth of the bones of the skull and brain, which is a consequence of a violation of the correlation of the endocrine glands, brain tumors, vascular nodes on the walls of the cerebral ventricles, and finally, a violation of the normal relationship between the blood pressure of the cranial fluid - all this can serve as the cause of increased intracranial pressure.

Spontaneous subarachnoid hemorrhage accounts for 5 to 10 % of all strokes, with a worldwide incidence of 10.5 / 100000 person/year, varying in individual reports from 1.1 to 96 /100000 person/year. Angiographic and autopsy studies suggest that between 0.5% and 5% of the population have intracranial aneurysms. Approximately 30000 people suffer aneurysmal subarachnoid hemorrhage in the United States each year, and 60% die or are left permanently disabled. We report our experience in the surgical treatment of intracranial aneurysms in a six year period, in Belo Horizonte, Minas Gerais, Brazil. We reviewed the hospital files, surgical and out-patient notes of all patients operated on for the treatment of intracranial aneurysms from January 1997 to January 2003. Four hundred and seventy-seven patients were submitted to 525 craniotomies for treatment of 630 intracranial aneurysms. The majority of patients were female (72.1%) in the fourth or fifth decade of life. Anterior circulation aneurysms were more common (94.4%). The most common location for the aneurysm was the middle cerebral artery bifurcation. The patients were followed by a period from 1 month to 5 years. The outcome was measured by the Glasgow Outcome Scale (GOS). At discharge, 62.1% of the patients were classified as GOS 5, 13.9% as GOS 4, 8.7% as GOS 3, 1.7% as GOS 2 and 14.8% as GOS 1.

Introduction: Arachnoid cysts are fluid-filled malformations of the arachnoid tissue. A prevalence in children of 2,6% has been reported[2,3]. Surgical strategies of treatment include open surgery with cyst wall excision , endoscopic fenestration or cystoperitoneal shunting[1,4]. Methods: In this video case, we described the case of a 1 year and 7 months old child who presented with motor development delay, unable to walk, who underwent microsurgical resection of a large posterior fossa arachnoid cyst and communication with the fourth ventricle. Conclusion: Microsurgery approach provides a safe anatomic control over the cyst and the recognition of floor of the fourth ventricle.
