title: Tentorial papillary meningioma in a child: case report and review of the literature.
abstract: We report a usual case of papillary meningioma arising from tentorium cerebelli occurring in a 13-year-old boy. This patient presented a 3-month history of a mildly poor coordination of the left side of his body. Computed tomography showed a homogenous enhanced mass lesion in the left posterior fossa. At surgery, gross total resection of the tumor was accomplished. Upon microscopic examination, some tumor cells were arranged in the papillary pattern and a resulting diagnosis of papillary meningioma was made. Electron microscopic studies showed typical meningioma features such as interdigitations and desmosomes, which were, however, detectable in only few tumor cells. Cytological and ultrastructural features of pediatric papillary meningioma and of high-grade meningioma in general are sparse. Since papillary meningioma rarely presents in children, we report this case and review the literature.
