Crush preparation cytologic findings of CNS tumors: a study of 199 cases

ABSTRACT

Crush preparation cytology technique was used during the operative procedure for the diagnosis of 199 CNS tumors. This technique is simple, easy to perform, rapid, and inexpensive. The cytomorphologic findings were excellent and helped achieve a rapid and correct diagnosis. This technique was used on the tiny, small specimens which were not suitable for frozen sectioning. The results were compared with biopsy reports. The overall diagnostic accuracy by this technique was about 97.7%
