Abstract
This study was conducted on 30 patients with intra-axial brain tumors in the period from September 2019 to February 2021. All patients underwent microsurgical excision with the help of intraoperative guiding imaging (neuronavigation and intraoperative ultrasound) with safety tumor resection in eloquent areas by intraoperative neurophysiological monitoring or awake craniotomy in the Neurosurgery Department, Tanta University Hospitals. The age of patients in the present study ranged from 4 to 75 years with a mean age of 42± 17.83 years at the time of surgery. In our study, pilocytic astrocytoma and medulloblastoma were presented at childhood age. Low-grade gliomas were more in the young adult patients while high-grade gliomas and metastatic tumors were mainly in the older age group. The most common preoperative symptoms of intra-axial tumors in the presenting study were seizures, focal neurological deficit, and symptoms of increase intracranial pressure as headache, vomiting, and blurring vision. Intra axial brain tumor has invasion growth inside brain parenchyma, so determining the tumor boundaries is very important for achieving the maximum extent of resection. Intraoperative guided imaging provides the goal of maximum resection of the tumor. Neuronavigation and intraoperative ultrasound are tools for imaging guiding surgery for evaluation of the extent of tumor resection and to estimate whether gross total resection was achieved or not.
