We report on a case of recurrent meningioma located in the left parietal region in a 47-year-old man. A smear/crush preparation obtained at the intraoperative consultation showed not only typical features of meningioma such as whorl formation and intranuclear cytoplasmic inclusions, but also an unusual cytomorphologic feature of a few mitoses. The diagnosis of atypical meningioma was established by the results of the histological and immunohistochemical stainings of the permanent sections. The present case indicated that cytology of smear preparations is useful in arriving at the final diagnosis of atypical meningioma.
