Ganglioglioma: comparison with other low-grade brain tumors.

Method: Forty-two patients with low-grade brain tumor and refractory epilepsy were studied. The mean age was 22.3 years.

[Intraoperative mapping of motor areas during brain tumor surgery: electrical stimulation patterns].

Unlabelled: Brain mapping with direct electrical stimulation is usefull when the tumor is located near or has infiltrated the central lobe.

Objective: To analyze the surgical findings with direct electrical stimulation of the cortex and white matter under general anesthesia during surgery for brain tumors related to the central lobe.

Method: We studied 42 patients operated on from June 2000 to June 2003.

[Partial epilepsy associated to primary brain tumors].

Objective: To characterize the epileptic syndrome of patients with primary cerebral tumor of slow growth.

Method: Clinical evaluation of fourty two patients with refractory epilepsy associated with cerebral tumor of slow growth were operated between June 1992 and September 1999.

Results: Almost 75% of the patients were less than 15 years old when they began the epileptic crises, 67.
