Cystic meningiomas are rare forms of meningiomas which are generally known as solid and benign tumours. Preoperative misdiagnosis of such a tumour will affect the surgical management and difficulties in histopathological diagnosis will affect the prognosis.

Flow cytometric studies have more advantages than histopathological studies, in postoperative management and in predicting prognosis, and it is better to use flow cytometry in conjunction with histopathological procedures for predicting the prognosis.

In this article we report flow cytometric analysis of three cystic meningioma cases, we correlate them with the histopathological results and discuss the pertinent literature.
