Diagnostic accuracy of cytology smear and frozen section in glioma

Introduction: Glioma is the commonest primary malignant brain tumour and diagnosis is based on cytology smear, frozen section and histopathological examination. Intraoperative pathological diagnosis using either cytology smear, frozen section or combination of both, plays a crucial role in patient’s...

Methods: A cross-sectional study was conducted involving 22 cases of glioma diagnosed intraoperatively from January 2013 until August 2019 in Hospital Universiti Sains Malaysia.
