Stereotactic support in the excision of brain tumors. Technical note

The surgical resection of deep-seated brain tumors may be facilitated by CT guided stereotactic methods. The Authors present a procedure of preoperative localisation and delimitation of the border of a neoplastic mass facing important functional areas. Ideally tumor excision should not be extended beyond that boundary which for this reason is targeted and is stereotactically labeled using non diffusible dyes.
