title: [Secretory meningioma. Report of two cases].
abstract: Two surgically removed meningotheliomatous meningiomas with hyaline inclusions or pseudopsammoma bodies were studied. Both meningiomas showed expression of carcinoembryonic antigen and cytokeratin in the cells surrounding the hyaline bodies. There was widespread vimentin and epithelial membrane antigen except in the cells with hyaline inclusions. Clinically both had a severe cerebral edema. One of the cases showed multiple tumors, probably meningiomas. It is important not to misinterpret this variant of meningioma as metastatic neoplasm which may result in palliative treatment of a potentially curable tumor.
