title: [Features in the diagnosis of meningiomas of the Sylvian fissure].
abstract: Examination of 12 patients with meningiomas of deep portions of the Sylvian fissure showed that at the early stages of the development of tumours the disease manifested clinically in intracranial pressure elevation and intellectual-mnemonic disturbances. Focal neurotic symptomatology is expressed at a later stage of the disease. The use of supplemental methods of examination, in particular of Echo EG, allowed localization of the tumor process in the area of the lateral sulcus in all cases. Preoperative identification of the histological structure of the neoplasm became possible only after angiography had been performed.
