[Stereotaxic approach in extensive lesions of the septum-fornix-callosal region. Apropos of 14 cases]. / L'approche stéréotaxique des lésions expansives intéressant la région trigono-septo-calleuse. A propos de 14 observations.

ABSTRACT

Stereotactic approach of anterior midline lesions which involve the septum-fornix-callosal region is a logical alternative to open surgery as a first choice. It contributes to know anatomical relations--particularly vascular and ventricular--of the lesion; it provides an accurate neuro-pathological diagnosis, with grading and spatial configuration of the lesion, and therapy in some cases. In other cases, it is a guide for appropriate therapeutic choice.
