The Value of Imprint Cytology in Diagnosis of Intracranial Tumors During Operation and Cytological Features of Intracranial Tumors / 中国医师杂志

ABSTRACT

Objective To evaluate the diagnostic accuracy of imprint cytology for intracranial tumors during operation. Methods 150 cases of intracranial tumors were diagnosed by imprint cytology. The imprint was prepared by touching the specimens several times with clean slide, and then the slides were fixed and stained with HE. The diagnostic results obtained by imprint cytology were compared with those made by frozen and routine paraffin sections. Results The accurant rates of diagnosing for non-glial tumors, classifying for incracranial tumors and grading for glial tumors were 100%, 91.3% and 88.3%, respectively. In addition, the morphological features of glial tumors, meningioma, pituitary adenoma on imprint cytology were briefly described. Conclusion The accurant rate of imprint cytology is almost equal to that of frozen section, and both the detection methods have a supplementary effect to each other.
