  • METHODS The University of California, San Francisco, tumor registry was searched for patients who, between 2010 and 2019, had undergone resection for newly diagnosed supratentorial diffuse glioma (WHO grades II-IV) performed by the senior author and who had at least 3 months of follow-up. (neurosurgery-blog.com)
  • Pre- and postoperative MRI studies were reviewed to confirm the tumor was located in the SMA region, and the extent of SMA resection was determined by volumetric assessment. (neurosurgery-blog.com)
  • Tumors were registered to a standard brain atlas to create a frequency heatmap of tumor volumes and resection cavities. (neurosurgery-blog.com)
  • Although the volume of tumor within the SMA region did not correlate with the development of SMA syndrome, patients with the syndrome had larger resection cavities in the SMA region (25.4% vs 14.2% SMA resection, p = 0.039). (neurosurgery-blog.com)
