Ультразвуковая и компьютерно-томографическая диагностика опухолей зрительного нерва

Abstract

A comprehensive examination was made in 93 patients, including 18 children, with tumors of the optic nerve (ON). Duplex ultrasound scanning was performed in 39 patients, of them there were 11 patients with ON gliomas and 28 with ON meningiomas. The specific computed tomographic and echographic signs of ON glioma and meningiomas were detected. The studies have shown that duplex ultrasound scanning and structural computed tomography of orbital sockets are highly informative complementary imaging procedures for ON tumors, which permits one to make their correct diagnosis, to specify surgical volume, and to plan adequate treatment.
