Abstract

Objective: To evaluate the initial outcomes of surgical resection of low-grade gliomas using intraoperative ultrasound guidance

Materials and Methods: A descriptive study combining retrospective and prospective data was conducted on 5 patients diagnosed with low-grade gliomas who underwent tumor resection with intraoperative ultrasound guidance at Saint Paul General Hospital from January 2021 to March 2026. Clinical characteristics, intraoperative ultrasound findings, extent of resection, and postoperative outcomes were analyzed.

Results: The mean age: 36.4 ± 2.3 years, M/F: 3/2. Headache (100%). Tumors predominantly in the frontal lobe (60%). Intraoperative ultrasound successfully identified tumors in all cases (100%), with hyperechoic features in 80%. Maximal tumor resection was achieved in 100% of cases, including gross total resection in 20% and near-total resection in 80%, fully consistent with postoperative MRI findings. Histopathology revealed WHO grade 2 astrocytomas (60%) and oligodendrogliomas (40%). All patients showed clinical improvement or remained stable postoperatively, with no recorded complications. The mean Karnofsky score improved from 84 ± 5.5 to 92 ± 4.5.

Conclusion: Intraoperative ultrasound is an effective tool in low-grade glioma surgery, enabling accurate tumor localization, maximizing safe resection, and improving postoperative clinical outcomes.
