Summary
Intraoperative smear cytology offers a fast and dependable method for diagnosing brain tumors during surgery. This study found crush smear cytology to be a valuable, accurate tool for neurosurgeons, aiding in craniopharyngioma diagnosis.
Area of Science:
- Neuropathology
- Cytopathology
- Neurosurgery
Background:
- Intraoperative smear cytology provides rapid diagnostic information during neurosurgery.
- It assists neurosurgeons in guiding surgical resection and modifying approaches.
- Accurate intraoperative diagnosis is crucial for patient management and outcomes.
Purpose of the Study:
- To evaluate the clinicopathological and cytomorphological correlation of intraoperative crush smear cytology in craniopharyngioma.
- To assess the accuracy and reliability of smear cytology for intraoperative diagnosis of central nervous system (CNS) tumors.
Main Methods:
- Retrospective analysis of 30 craniopharyngioma cases diagnosed via intraoperative crush smear cytology.
- Correlation of cytomorphological findings with histopathological diagnoses and clinical/radiological data.
- Calculation of error rates and assessment of diagnostic discrepancies.
Main Results:
- The study included 30 craniopharyngiomas (27 adamantinomatous, 3 papillary).
- An overall error rate of 14% was observed, with discrepancies in tumor typing and incomplete cell typing.
- Correlation with clinical and radiological findings improved diagnostic accuracy.
Conclusions:
- Intraoperative crush smear cytology is a valuable, accurate, safe, and cost-effective tool for diagnosing brain tumors, particularly in CNS pathology.
- Cytological features and smear patterns provide essential complementary information for histopathological examination.
- Smear cytology aids neurosurgeons in real-time surgical decision-making.
