Meningioma's account for around 15% of all primary brain tumors with some 10% of meningiomas arising in the posterior fossa. In rare cases, a meningioma can form around the endolymphatic sac. When formed in the posterior fossa, meningioma tumors can produce vague, non-specific vertiginous symptoms. Research has observed that a subset of these lesions could produce symptoms indistinguishable fro...

AIM To assess the effectiveness and safety of pre-resection endoscopic third ventriculostomy (ETV) in permanently relieving hydrocephalus in children with posterior fossa tumors. MATERIAL AND METHODS 17 pediatric patients with posterior fossa tumors and associated triventricular obstructive hydrocephalus underwent ETV before definitive tumor resection, and ETV was repeated after tumor resecti...

Introduction: Teratomas are non-malignantgerm cell tumors commonly composed of cell types derived from all of the three germ layers. Intracerebral teratomas typically are midline or paraxial lesions located in the pituitary stalk or the pineal region. We report our experience with mature teratomas of the posterior fossa. Case report: We present the case of an 11-yearold caucasian female with pr...

Intracranial tumors are the second most frequent malignancies in children and posterior fossa is a common location for these neoplasias during childhood. Recent advances in surgical techniques, radiotherapy and chemotherapy resulted in dramatic increase in the survival rates of these children, however they are still source of a significant morbidity and mortality. Endocrinological complications...

Medulloblastoma is common in children as a tumor of midline posterior fossa, which arises from vermis and appears as a homogenously enhancing hyperdense mass on computed tomography scan and is associated with the clinical picture of posterior fossa syndrome. This unique clinic-radiological pattern in considered "typical" medulloblastoma, but medulloblastomas does not follow the typical clinic-r...

Received 10 February 2014 Accepted 26 July 2014 Online 31 July 2014 Print 31 July 2014 Tumors of the posterior fossa of brain leads to complications like brain stem compression, herniation and death because of its critical location, limited space and involvement of vital brain stem nuclei. This study has been conducted in the department of Pathology and Neurosurgery, Gandhi Medical College, Sec...

A 28-year-old man was admitted due to progressive headache and blurred vision. Neurologic examination showed bilateral papilledema. Brain MRI showed a cystic posterior fossa tumor compressing the fourth ventricle with tonsillar herniation and cervical syringohydromyelia (figure 1). The tumor was removed through a suboccipital craniectomy and pilocytic astrocytoma was diagnosed histologically. O...

Medulloblastoma is the most common malignant and uncontrollable childhood brain tumor. This tumor is observed in patients of all ages, reaches a peak in children between 3 and 9 years old, and it is also the most common malignant cerebellar tumor in infants. It accounts for 1% to 2% of all brain tumors in adults. By definition, medulloblastomas arise in the posterior fossa, but histologically s...

Objective: Aim of the study was to assess the duration of preoperative external ventricular drain (EVD) as a predictor for permanent cerebrospinal fluid (CSF) diversion in pediatric posterior fossa tumors. Methods: The study was conducted in the Department of Pediatric Neurosurgery, National Neuroscience Institute, King Fahad Medical City, Riyadh, Saudi Arabia from January 2010 to December 2013...
