Parasagittal meningioma often presents as peritumoral brain edema (PTBE). The risk of edema increases when the tumor occludes the superior sagittal sinus (SSS). Although PTBE may be expected based on the patient's symptoms or radiologic findings, extensive brain swelling and extracranial herniation during elective surgery are rare. Herniation during surgery could lead to irreversible neurologic...

Introduction. Brain tumors are a complex problem of modern neurosurgery. Meningiomas, mostly benign tumors, can become when they difficult to locate. The complexity is also caused by affecting the sinuses brain. In this case, surgeon faces number issues related diagnosis, preoperative planning and choice treatment tactics for these patients. in favor revascularization venous bed not always unam...

brain tumors in elderly are increasing as the number of people, who comprise the older population, does.about half of the patients with brain tumors appear to be over 60 years of age.in this review article, glioblastoma multiform, as the most common malignant tumor of the central nervous system in elderly is discussed in details of definition, prognosis, diagnosis, treatment and differential di...

BACKGROUND The incidence rate of pulmonary emboli (PE) is high in tumor patients; however, the morbidity and mortality associated with the development of PE after tumor surgery are unknown. We studied the clinical profiles and outcomes of patients with PE after non-brain tumor surgery. METHODS We retrospectively screened 55,967 patients who underwent non-brain tumor surgery at the Peking Univ...

Neuroimaging has evolved from Computed Tomography (CT), CT-Positron Emission Tomography (CT-PET) and Magnetic Resonance Imaging (MRI) scanner in 1970s and 1980s to functional MRI (fMRI), Diffusion Tensor Imaging (DTI) and Magnetic Source Imaging (MSI) or Magnetoencephalography-MRI (MEG-MRI) fusion in 1990s and 2000s. Anatomical and functional neuroimages are currently regarded by most as vital ...

BACKGROUND Abnormalities on magnetic resonance imaging scans are common both before and after surgery for congenital heart disease in early infancy. The aim of this study was to prospectively investigate the nature, timing, and consequences of brain injury on magnetic resonance imaging in a cohort of young infants undergoing surgery for congenital heart disease both with and without cardiopulmo...
