[Deep Sylvian psammomeningioma, report of a case (author's transl)].

The authors reported a case of 31-year-old female who had episodes of fainting attack. She had no significant neurological deficit but had EEG abnormality. Carotid angiography showed a tumor stain, ca. 1.7 cm in diameter, near the right insula. CT scan also revealed a high density area at the same site. At the time of operation, a small tumor located deeply in the right sylvian fissure was found out and successfully removed. Histologically, this tumor was diagnosed as a meningioma having some typical psammomatous features. This type of meningioma, named as deep sylvian psammomeningioma dy Cushing and Eisenhardt, is extremely rare; we could found only 19 cases in the literature.
