Papillary meningioma with pleural metastasis: case report and literature review

Papillary meningiomas are rare meningeal tumors which are associated with a grim prognosis. These tumors usually recur locally and in some cases they metastasize. The clinical, radiological and histopathological features of a case of a papillary meningioma with a pleural metastasis in a 13-year-old boy are presented. The literature on metastasizing papillary meningiomas is reviewed. Up to now, 131 cases of papillary meningioma have been reported in the literature. Only 8 cases gave rise to metastases outside the central nervous system. The preferential site of metastasis appeared to be the lun g. This is the first report of a papillary meningioma giving rise to a meta stasis in the pleura.
