Squash cytology of clear cell meningioma: Report of a case

Clear cell meningioma (CCM) is a rare histological variant of meningioma. It is commonly located at the cerebellopontine angle and the spine particularly around the cauda equina. Squash cytology finding of meningioma is well-established, however there is sparse literature available on squash cytology of CCM. Here we describe a case of CCM occurring in the lumbar spine in a young woman. Initially, on squash cytology a diagnosis of a low grade glioma favouring an ependymoma was considered. Eventually histopathological examination along with immunohistochemistry helped us reach the diagnosis of a CCM. In this article we discuss the cytomorphology of CCM along with its cytological differentials and the hurdles to an accurate diagnosis.
