OBJECTIVE The aims of this study were to characterize the epidemiologic, histologic, and radiologic aspects of sphenopetroclival meningiomas (SpPCMs) and to evaluate the outcome of Gamma Knife radiosurgery (GKRS) either as an adjunct to microsurgery or as a primary SpPCM treatment modality. METHODS In this retrospective study, medical records of patients(More)
Background: Neuroendoscopic system is the best choice for detection and assessment of intracranial cysts and intraventricular tumors and cysts. There are some reasons and features for neuroendoscopy to be the number-one option for these dysfunctions such as entrapment of cerebrospinal fluid (CSF) inside the arachnoid cysts, location of intraventricular(More)
Background: The present study aims to evaluate the Graded Prognostic Assessment (GPA) score for predicting overall survival in patients diagnosed with brain metastases undergoing Gamma-knife radiosurgery. Methods: This was a cross sectional study conducted on the patients diagnosed with brain metastases undergoing Gamma-knife radiosurgery during 2003 to(More)
