Intraoperative frozen section (FS) examination represents an essential diagnostic modality in neurosurgical pathology, enabling rapid pathological interpretation that directly influences intraoperative clinical decision-making. The reliability of frozen section diagnosis depends not only on diagnostic accuracy but also on the completeness and quality of documentation, which collectively determine communication efficiency between pathologists and neurosurgeons. Despite technological advancements in neuropathology, discrepancies between frozen section diagnoses and final histopathological findings remain a recognized challenge, particularly in central nervous system (CNS) lesions characterized by marked morphological heterogeneity. Furthermore, inadequate documentation may compromise diagnostic traceability, quality assurance, clinical auditing, and patient safety. This research and review article presents a comprehensive tertiary care audit evaluating both diagnostic accuracy and documentation quality of intraoperative frozen sections in CNS lesions. A structured audit methodology was developed using established pathology reporting principles, documentation quality indicators, and diagnostic concordance measures. Diagnostic outcomes were categorized into concordant, partially concordant, and discordant findings relative to permanent paraffin-section diagnoses, while documentation quality was evaluated through predefined completeness parameters including specimen identification, clinical history, radiological correlation, provisional diagnosis, interpretative comments, communication records, and reporting signatures. The analytical framework demonstrates that systematic auditing serves as an effective quality improvement mechanism capable of identifying procedural deficiencies and enhancing reporting consistency. Comparative interpretation of available literature indicates that standardized documentation practices substantially improve diagnostic transparency and facilitate multidisciplinary decision-making (Davis et al., 2019). The study further emphasizes that institutional audit systems contribute to continuous professional development, quality accreditation, and patient-centered diagnostic services. Although frozen section examination remains associated with intrinsic technical limitations arising from sampling constraints and tissue artifacts, structured documentation protocols significantly strengthen overall diagnostic reliability. The findings support the integration of routine audit cycles, standardized reporting templates, and documentation quality indicators within tertiary neuropathology services to optimize diagnostic performance and healthcare quality.
