| Abstract: | Twenty-three meningiomas and 14 neurilemomas were studied by frozen section and crush-preparations techniques. These two types of tumors displayed distinctive cytologic pictures, permitting a correct identification in all cases. Six cases of deeply seated and unusually located meningioma and neurilemoma with equivocal or erroneous frozen section diagnoses were correctly diagnosed cytologically in the crush preparations. |
