Abstract

Meningioma is the benign, unencapsulated neoplasm arising from meningo-epithelial arachnoid cells of cerebellopontine angle-internal auditory canal dura but extracranial meningiomas are very rare. In making the diagnosis of invasive meningioma, both changes of benign meningioma and invasive growth should be present. A case of the neglected invasive meningioma is described here which invaded approximately half of the fronto-temporo-parietal skull vault. The diagnosis was established and confirmed by the histopathology and immunohistochemistry, the cells were positive for epithelial membrane antigen, vimetin and progesterone receptors. The patient underwent surgical resection.
