title: Secretory meningioma: a case report with immunohistochemical and ultrastructural study.
abstract: Secretory meningioma is a new concept proposed with the progress on immunohistochemistry, and has not sufficiently been discussed in the literature. We report a case with this rare type of meningioma, in a 54-year-old female. The tumor had hyaline inclusions that showed not only carcinoembryonic antigen (CEA) on immunohistochemical study but some secreting organelles on ultrastructural study. The value of these findings are emphasized in the histological diagnosis for secretory meningioma.
